Hunting ten-year five-baggers among great growth stocks — pressing the upside question: "Can it get much bigger?"

• QHow high is its market ceiling? Is it growing a slice of an existing pie, or creating an entirely new market?5/10

  A

  The ceiling isn't low, but it falls into the "growing a slice of an existing pie" category, and AvalonBay itself only holds a very thin slice of it; this hardly counts as "creating an entirely new market."

  Let's size the market first. The U.S. is one of the largest rental housing markets in the world, with about 44+ million renter households; the research report also cites the company's shareholder letter using the figure "45 million U.S. households choosing to rent." On a household basis, this means the addressable demand pool is enormous, but that's exactly why this is a mature, essential-demand market that has existed for over a century, not a new track created out of thin air by some technology or business model. What Baillie's LTGG strategy favors is "defining a market that didn't previously exist" (the kind cloud computing, EVs, or e-commerce payments represent); AvalonBay doesn't belong in that category; it's competing for a slightly larger slice of a huge but slow-growing existing pie, and trying to run its own slice better.

  Looking at the share AvalonBay can actually reach, the "imagination space" of the ceiling gets compressed quite a bit. As of the end of Q1 2026, the company held 319 communities and 98,271 apartment homes, spread across 11 states and Washington, D.C. Put that into the national rental pool of 44 million units, and the penetration rate is under 0.3%. And the company is deliberately focused: it defines New England, New York/New Jersey, Mid-Atlantic, Pacific Northwest, and California as Established Regions, actively forgoing a large share of the Midwest and South. So its serviceable addressable market (SAM) is far smaller than the national TAM: it's upper-middle-to-upscale apartments in high-barrier, high-home-price coastal/high-income metro areas: a slice of pie that's high quality, but limited in incremental size.

  The company itself seems aware of the ceiling on "slowly penetrating the existing pie," and has chosen to enlarge its share in one shot through M&A rather than creating new demand organically. On May 21, 2026 the company announced an all-stock "merger of equals" with Equity Residential; the combined company will hold more than 180,000 apartment homes, with about $52 billion in pro forma equity value and about $69 billion in enterprise value. But this is "stitching two existing pies together": the merger materials disclose that about 95% of the two companies' combined NOI is concentrated in overlapping regions, relying on going deeper and denser in the same batch of high-value metros, not opening new frontiers. Even so, the combined 180,000 units against a national pool of 44 million units is still only a single-digit-per-thousand share.

  Conclusion: the "absolute size" of the ceiling is large (trillion-dollar-scale national rental spending), but for AvalonBay this is a market of growing an existing pie, with the penetration ceiling doubly constrained by its own regional focus and asset-heavy nature; there's no "creating an entirely new market" component. By Baillie's yardstick of "can the ceiling support a ten-year fivefold," this dimension isn't a standout: its upper bound comes from going deeper and denser in good regions and running operations more efficiently, not from explosive expansion of the market itself.

• QCan its revenue at least double over the next five years? Is growth driven mainly by volume, price, or new business lines?3/10

  A

  Almost impossible. Doubling AvalonBay's revenue over five years (roughly 15% annualized) sits sharply at odds with the nature of its business and its own guidance; growth is driven mainly by "price" (rent resets) at a modest pace, "volume" (new apartment homes) is a slow-moving variable, and there simply isn't a "new business" that could carry a doubling.

  Start with what the company itself says about 2026. AvalonBay's full-year guidance is for modest growth, not acceleration: full-year same-store residential revenue growth guidance is about 1.4% at the midpoint, Core FFO/share growth is only about 0.1%, while operating expenses are expected to rise about 3.8%, pushing same-store NOI growth to just about 0.3%. Q1 actuals confirm this: Q1 2026 same-store residential revenue grew 1.6%, same-store NOI grew only 0.2%, with expenses staying tight. A company whose management has framed 2026 as a "transition year" makes talk of doubling revenue in five years unrealistic.

  Now look at the historical growth slope. The company's Core FFO/share rose from $9.79 to $11.24 between 2022 and 2025, a cumulative gain of about +14.8% over four years (only about 3.5% annualized); operating cash flow rose from $1.422 billion to $1.671 billion, also low-single-digit compounding. This slope is an order of magnitude short of "doubling in five years": doubling requires about 15%/year, while AvalonBay has long run at 3%–5%.

  Breaking down the sources of growth, none of the three engines has doubling-level torque:

  • Price: apartment leases generally run one year or less and can be reset frequently, giving some theoretical inflation pass-through. But of the 2.5% same-store residential revenue growth in 2025, only 1.9 percentage points came from rent levels, 0.1 percentage points from occupancy, and 0.6 percentage points from other lease revenue; the magnitude of rent increases is constrained by supply and residents' ability to pay, and can't reach double digits.
  • Volume: expanding assets via the development pipeline. As of the end of Q1, under-development projects had an estimated total capitalized cost of about $3.39 billion, against a total asset base of nearly $20 billion for the company; net annual capacity additions are a single-digit percentage, and the development cycle is measured in years, with sold assets also netted out (the company sold 9 communities in 2025).
  • New business: management/development/other fee income was only $1.833 million in Q1 2026, essentially negligible; the company is still fundamentally a rent collector with no second growth pillar capable of contributing revenue at scale.

  The only thing that could produce a step-change jump in "revenue" within five years is M&A: the all-stock merger with Equity Residential will form a platform of more than 180,000 units, and the combined entity's revenue will be close to double. But this is an accounting-basis combination, not AvalonBay organically doubling its own business; for existing AVB shareholders, you receive 2.793 EQR shares per AVB share and hold about 51.2% of the combined company; per-share revenue hasn't doubled, and what you get in return is cost savings such as about $175 million of gross synergies/$125 million of net synergies (realized within 18 months), not a revenue explosion.

  Conclusion: by Baillie's "five-year revenue doubling" yardstick, AvalonBay clearly falls short. It's a mature, slow-growth business driven modestly by "price," climbing slowly on "volume," with no new-business torque; the only "doubling" comes from consolidation accounting, not from any change to the fact that organic per-share growth remains low single digits. This dimension is a weak spot.

• QFive years from now, what will take over as the next growth engine? Does this "second curve" exist today?4/10

  A

  Frankly, AvalonBay doesn't have anything that qualifies as a "second curve": what takes over five years from now is still an extension of the same primary curve (development pipeline delivery + deeper regional density + operating efficiency), not a new business that already exists today and could build an entirely new growth pillar.

  Let's look at the "growth sources" the report names one by one, and judge whether each is a genuine second curve:

  First, the development pipeline. As of the end of Q1 2026, under-development projects had an estimated total capitalized cost of about $3.39 billion, and new development started in 2025 had a total capitalized cost of $1.636 billion. This is the primary engine of AvalonBay's NOI growth over the next few years, but it's essentially a natural extension of the primary curve: keeping the existing "buy land, develop, hold and collect rent" flywheel turning, still producing the same kind of homogeneous apartment NOI, not a new species. Once development yields get compressed close to the cost of capital by interest rates, this engine will slow down.

  Second, operational transformation (the operating-efficiency moat). The report cites the shareholder letter, where the company expects to add about $7 million of NOI from operational transformation in 2026, about 70% of the way toward its long-term target of about $80 million of incremental NOI. This is genuine organic improvement (centralized services, technology and data investment amortizing costs), but it's "making the same business leaner," and its contribution to NOI is incremental and capped ($80 million against Core FFO in the billions is a single-digit percentage), so it doesn't constitute a second curve capable of doubling the business.

  Third, AI/digitalization/data advantage. The company repeatedly emphasizes this in its shareholder letter and merger materials, but the report itself honestly characterizes it as "icing on the cake, not a core moat." It can improve pricing, marketing, and maintenance scheduling, but it still lands on making existing apartments more efficient, not an independent, externally monetizable new business line; management/development/other fee income of just $1.833 million in Q1 2026 is evidence of that.

  Fourth, the post-merger platform. This is the closest thing to "taking over," but what it replaces is "the corporate entity" itself, not "the growth curve": if the all-stock merger with Equity Residential completes in 2H 2026, AVB shareholders will hold about 51.2% of the combined new company; five years from now, what you "hold" will be this new entity of 180,000+ units and about $69 billion enterprise value. But the merger's growth logic is still apartment rent collection plus about $125 million of net synergies (cost savings), not opening a new market. In other words, it makes the scale bigger, but doesn't deliver a growth engine of a different nature.

  Putting these four together: AvalonBay's "next engine" and its "previous engine" are different gears on the same machine: deeper regions, more buildings, leaner operations, bigger scale, all converging on the same rent-collecting business. Baillie's question about whether a "second curve exists today" is trying to find something like AWS was to Amazon's e-commerce: a whole new mountain built alongside the core business. AvalonBay doesn't have anything like that, and is unlikely to, because its asset characteristics (asset-heavy, long-cycle, geographically rooted) make it very hard to cross into a new business cheaply.

  Conclusion: this dimension is a weak spot. Five years from now, AvalonBay's growth will still be handed off through "development delivery + operational efficiency gains + merger synergies," but these are all extensions of the primary curve or a one-time scale combination; there is no genuinely independent second curve. For a growth investor seeking "tenfold in ten years," this is a clear ceiling.

• QWhat is its core competitive advantage? Will this moat widen or narrow over the next three to five years?5/10

  A

  The core competitive advantage is supply barriers in high-barrier regions + a development and operating platform built on regional clustering density + consistent, rational capital allocation; this moat genuinely exists, but it's the "stable, modestly widening, not steep" type, and over the next three to five years it will most likely hold rather than widen significantly.

  Start with the part that looks most like a moat: supply barriers. AvalonBay defines New England, New York/New Jersey, Mid-Atlantic, Pacific Northwest, and California as Established Regions, where land, entitlement, and permitting constraints keep new supply structurally limited long term; the report cites the company's own figures showing new supply in its Established Regions in 2026 is expected to equal only about 80 basis points of existing stock. This kind of region doesn't guarantee high growth every year, but it meaningfully raises the difficulty for a new entrant to replicate a comparable asset portfolio; this is where AvalonBay comes closest to a "structural moat," and since it's determined by geography and regulation, it won't weaken over the next three to five years.

  Second is scale and regional density. The scale that truly matters isn't "spreading out more nationally," but "going deeper and denser in the same high-value regions," which amortizes data, technology, local service, and purchasing costs. This has been made explicit in the merger materials: after the merger with Equity Residential, about 95% of the two companies' combined NOI is concentrated in overlapping regions, expected to generate about $175 million of gross synergies, or about $125 million of net operating synergies after re-assessed real estate taxes. The merger simply amplifies and realizes the "density economics" AvalonBay already had standalone, showing this moat is market-recognized and quantifiable.

  Third is capital allocation capability, which is often the real source of a REIT's long-term excess returns. AvalonBay's actions are highly consistent: breaking ground when development spreads are favorable, buying back stock when public and private market valuations diverge, and selling single assets that no longer fit the portfolio to redeploy capital. In 2025 the company sold 9 communities for proceeds of $812 million, acquired 12 communities for $826 million, started new development with total capitalized cost of $1.636 billion, and simultaneously repurchased $488.1 million of stock (at an average price of $182.20/share), followed by another $198 million of buybacks (average price $175.59) in Q1 2026. This discipline is a soft but durable advantage.

  But it's worth honestly pointing out the moat's boundaries and vulnerabilities:

  • It's not a brand moat. Avalon/AVA/eaves have some recognition at the upper-middle tier (the company claims record resident NPS and retention), but apartments aren't a Coca-Cola-style brand, and the premium is limited.
  • Switching costs are moderately weak. Residents can move, and retention depends on experience rather than lock-in; it loosens when regional supply is released or promotions kick in.
  • There's no network effect. The report itself characterizes the data/AI advantage as "icing on the cake," not a core barrier.
  • It's rate-sensitive, which erodes the "cost-of-capital advantage". With the 10-year Treasury yield currently around 4.5%+, sustained high rates compress a REIT's financing-cost advantage and development-return spread; this is the part of the moat most easily eroded by the external environment.

  Will it widen or narrow over the next three to five years? My judgment is broadly stable, modestly widening: supply barriers and regional depth won't weaken, the development and operating platform continue to strengthen, and if the merger completes it will further cement the density economics (the widening part); but rising rates erode the cost-of-capital advantage, and near-term supply releases compress pricing power (the narrowing counterweight). The two forces roughly offset, so the moat is more likely to be "slowly reinforced" than "steeply widened."

  Conclusion: the moat dimension is one of AvalonBay's relatively solid items among Baillie's ten questions: there's a real, quantifiable supply and density barrier, validated by merger synergies; but it's a defensive, efficiency-type moat, without the kind of accelerating expansion characteristic needed to drive "tenfold in ten years." Over three to five years it will get steadier and modestly wider, not increasingly faster.

• QIf its core business were disrupted, does it have the DNA to reinvent itself? How does it handle mistakes and bad news?4/10

  A

  The probability of "core business disruption" is inherently low for a physical apartment business rooted in high-barrier regions; what really matters is its attitude toward mistakes and bad news; here AvalonBay comes across as fairly restrained and honest, though its "self-reinvention DNA" is of the incremental-experimentation kind, not the dramatic-pivot kind.

  First, let's frame how realistic "disruption" actually is. The underlying demand for apartments is essential housing need, and the probability of it being wholesale disrupted by a single technology or new model is extremely low: people always need somewhere to live; remote work, co-living, and long-term-rental securitization only change the spatial distribution and product form of demand, not eliminate it. The report also frames the industry as "a cyclical sub-industry within a mature industry," with structural demand supported by about 45 million renter households, later marriage and childbearing, and high home prices/mortgage rates making "renting more cost-effective than buying." So this business doesn't face "disruptive extinction"; it faces cyclical erosion from interest rates, supply, and regional competition. For this kind of risk, the more relevant question isn't "can it reinvent itself," but "does it tell the truth and respond rationally when bad news arrives."

  And on "how it handles mistakes and bad news," AvalonBay earns credit:

  • It doesn't sugarcoat low growth. The company's 2025 shareholder letter states plainly that 2026 assumes only about 1.4% same-store revenue growth and about 0.1% Core FFO/share growth, laying out soft demand and low job growth clearly; Q1 also honestly disclosed same-store NOI growth of only 0.2%, with expenses tight. This "tell it like it is" communication is more trustworthy than an inflated narrative.
  • It acknowledges valuation divergence and corrects with action. Management framed the 2025 buybacks as an opportunity from "the divergence between public-market and private-market apartment valuations," and on that basis repurchased $488.1 million of stock in 2025 (average price $182.20), followed by another $198 million in Q1 2026; this is the corrective act of "buying back when you spot your own stock mispriced," not putting on a show at the top to juice EPS.
  • Asset rotation as "acknowledging and correcting allocation mistakes." Selling single assets that no longer fit the portfolio and redeploying (selling 9 communities and buying 12 in 2025) is a continuous form of self-pruning.
  • Governance has a correction mechanism. The company has a clawback policy; its 2025 disclosures show no accounting restatements requiring clawback of executive compensation.

  But "self-reinvention DNA" should be discounted. AvalonBay's "reinvention" is more of a fine-tuning along the core business (operational-efficiency transformation, digitalization experiments, scaling up via M&A) rather than the kind of decisive pivot to a new species some tech companies make when their core business is threatened. Its asset characteristics (asset-heavy, long-cycle, geographically rooted) mean it turns slowly and faces high costs of experimentation; it simply can't "agilely tear it all down and start over." The step that comes closest to "self-renewal" is actually using M&A to respond to the bad news of "slow organic growth": recognizing the ceiling on independently growing its share, it chose an all-stock merger with Equity Residential to expand in one shot and realize density synergies. That counts as a proactive response to a structural bind, but it's "getting bigger," not "reinventing itself."

  Conclusion: this dimension isn't a weak spot for AvalonBay, but it isn't a highlight either. Disruption risk is inherently low; its attitude toward mistakes and bad news is honest, restrained, and disciplined about correction (candid guidance, counter-cyclical buybacks, asset rotation, clawback), which deserves credit. It just lacks the kind of dramatic regenerative capacity Baillie favors: "growing a whole new self even when the core business is threatened." Its "reinvention" ceiling is leaner, bigger, denser, not a metamorphosis.

• QDoes management (especially the founder) have a long-term view, with interests deeply tied to the company? Are they willing to sacrifice current profit for the sake of five to ten years from now?4/10

  A

  Management passes on "long-term view, rationality, honesty," and its capital-allocation discipline is a genuine plus; but on "interests deeply tied to the company" the degree is average: this is a company led by professional managers rather than controlled by a founder, with a relatively low level of insider ownership. Is it willing to sacrifice current profit for five to ten years out? Yes, but it's the "steady and restrained" kind of sacrifice, not the moonshot kind.

  Start with the alignment structure, the area Baillie weighs most heavily and where AvalonBay is relatively weakest. The company has clear executive stock-ownership requirements: the CEO must hold 6x salary, the CFO and executive vice presidents 3x salary, and all covered executives with five or more years of tenure have met these requirements; CEO Benjamin Schall holds about 132,882 shares, and CFO Kevin O'Shea holds about 48,750 shares. Directionally this is aligned. But the crux is the absolute magnitude: the report discloses that all current directors and executive officers combined hold only about 0.53% of shares outstanding. Converting to dollar terms, at AVB's current share price of about $186.59 and market cap of about $26.6 billion, 0.53% is worth about $140 million, not small for a group of executives, but relative to the company's size it's "ownership, not control." This isn't the "management itself is a major shareholder" kind of strong alignment, and there's no founder with personal wealth on the line to create that kind of interest alignment. AvalonBay was never a founder-led company to begin with, so the "deep founder alignment" Baillie favors is structurally absent here.

  Now for vision and honesty, where AvalonBay performs well:

  • It doesn't lean on inflated narratives. Management honestly framed 2026 as a low-growth transition year (full-year same-store residential revenue guidance of about 1.4% at the midpoint, Core FFO/share growth of about 0.1%), laying out soft demand clearly.
  • Capital allocation is highly rational and long-term oriented. Breaking ground only when development spreads are favorable, buying back when valuations diverge, selling underperforming assets to redeploy. In 2025 the company sold 9 communities for $812 million, acquired 12 communities for $826 million, started $1.636 billion of new development, and simultaneously repurchased $488.1 million of stock (average price $182.20), followed by another $198 million (average price $175.59) in Q1 2026. The buyback prices landed roughly around today's price, showing it's willing to return capital in a reasonable valuation range rather than posture at highs.
  • Governance constraints are reasonable. It has a clawback policy and requires shareholder approval for excessive severance; potential dilution is manageable: as of March 2026, about 849,400 shares granted-but-unvested/unexercised, for basic dilution of about 0.61%, with potential total basic dilution of about 3.48% if the 2026 incentive plan is approved, which isn't outlandish.

  Is it willing to sacrifice current profit for the long term? The answer is yes, evidenced by consistently putting large amounts of cash into a development pipeline that produces nothing in the current period and won't contribute NOI for years: as of the end of Q1, under-development projects had an estimated total capitalized cost of about $3.39 billion, itself a posture of sacrificing near-term distribution capacity for long-term growth. But this sacrifice is steady investment "within a disciplined spread framework," not the aggressive style of betting cash flow on a distant vision, a fundamentally different type from the "founder willing to burn cash for a decade from now" Baillie favors.

  One structural change worth flagging: if the merger with Equity Residential completes, Schall will become CEO of the combined company, and future capital-allocation logic will partly shift to the new company level, governed by a 14-person board of equals; this means the "AVB management" you're assessing today isn't exactly the same decision-making body as the "combined-company management" you'll actually end up holding.

  Conclusion: the management dimension is one of AvalonBay's middle-to-upper items among Baillie's ten questions: rational, restrained, honest, willing to buy back counter-cyclically, with correction and governance discipline, and worth trusting; but "deep alignment" isn't strong enough (all directors and executives combined hold only about 0.53%, no founder control), and its willingness to sacrifice the short term for the long term is steady rather than risk-taking. Give it trust, but don't expect founder-level interest alignment or a bold long-term bet.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable, without relying on harm to society or regulatory arbitrage?5/10

  A

  If AvalonBay disappeared tomorrow, its residents would be "inconvenienced" but not "left without alternatives"; indispensability is moderate-to-weak; the good news is its growth model is highly healthy and doesn't rely on harming society or skirting regulatory lines, so the social/regulatory-sustainability side is solid. The two sub-questions are one weak, one strong.

  Start with "indispensability." AvalonBay's customers are dispersed individual residents, not a handful of accounts it can't do without; this is an advantage for risk resilience (no concentration risk of "losing one big customer does serious damage"), but it's precisely a weakness on "indispensability": any single resident's dependence on any single landlord is low. Residents can in theory move next door to an EQR, UDR, ESS, or any comparable apartment in the same area; switching costs are just the friction of moving, deposits, commutes, and school districts, not the kind of strong lock-in a software subscription has. The report itself honestly characterizes switching costs as "moderate-to-weak." What keeps people is experience (the company claims its best-ever resident NPS and record retention in 2025), but that's "you stay because it's good," not "you can't function without it." So the answer to "how much would residents miss it if it disappeared tomorrow" is: they'd feel it's a pity and it would take some effort to find an alternative, but the market has comparable upscale apartment supply to fill the gap, so the degree of missing it is limited.

  What genuinely raises its "regional-level indispensability" is the supply barrier, not the brand: in Established Regions with constrained land and permitting like New England, New York/New Jersey, and California, equivalent-quality homes can't be built quickly in the short term: the report cites the company's figures showing new supply in these regions in 2026 is expected to equal only about 80 basis points of existing stock. So in specific high-barrier locations, AvalonBay's assets carry some "scarcity premium," but that's "good housing in this location is scarce," not "this brand is irreplaceable."

  Now for "is growth sustainable without harming society or regulation": this is clearly a plus for AvalonBay:

  • The growth model is healthy. It earns money by providing a genuine housing product and charging market-rate rent, driven by rent resets (2025 same-store residential revenue growth of 2.5%, of which rent levels contributed 1.9 percentage points), occupancy (Q1 2026 economic occupancy of 96.1%), and new development supply, not predatory price gouging or regulatory arbitrage. It's actually adding to, not reducing, housing supply: the total capitalized cost of new development started in 2025 was $1.636 billion, net new homes added in high-barrier regions, which aligns with the direction of social need.
  • Regulatory risk is moderate and the business operates within the rules. Apartment REITs do face policy variables like rent control, local housing policy, and development approvals (New York, California, and others have a history of rent regulation), rent growth is softly constrained long term by residents' ability to pay and local regulation, but this is "operating within the rules" rather than "a business model built on a regulatory gray zone that could snap back." It doesn't carry the kind of overhanging systemic regulatory-crackdown risk that data-privacy abuse, platform monopoly, or environmental violations do.
  • The regulatory side of the merger is also relatively clean. The all-stock merger with Equity Residential requires shareholder approval and is expected to complete in 2H 2026; the apartment industry is highly fragmented (the combined 180,000 units against the national rental pool of about 44 million is still only single-digit-per-thousand), which doesn't constitute market dominance in an antitrust sense, so regulatory resistance is relatively manageable.

  Conclusion: this dimension is half weak, half strong for AvalonBay. "Indispensability" is moderate-to-weak: customers are dispersed, switching costs aren't high, the brand doesn't lock people in, and scarcity comes from location rather than the enterprise itself; but "social/regulatory sustainability" is solid: it grows healthily by adding genuine housing supply and charging market rents, without relying on harm to society or regulatory overreach. Overall, it isn't the kind of business users would be devastated to lose, but its growth is clean and sustainable and won't be upended by regulation over five to ten years due to any "original sin" in how it grows.

• QHow are this business's unit economics (gross margin, incremental returns)? Do they improve or worsen with scale? Where does the cash it earns get spent?5/10

  A

  Unit economics are "quality cash cow" grade (high NOI margin, real and ample cash flow, a sound balance sheet), but it's a business that's asset-heavy and requires continuous, substantial reinvestment to sustain its competitiveness, with incremental returns on capital only in the mid-to-high single digits; getting bigger mainly delivers "cost synergies," not "a step-change in margin." The cash it earns goes toward development, acquisitions, buybacks, and dividends, allocated rationally.

  Start with profit quality and the "gross margin" equivalent. For an apartment REIT, the closest thing to "gross margin" is the NOI margin, and AvalonBay's property-level margin is high: 2025 net income attributable to common stockholders was $1.051 billion, but Core FFO reached $1.606 billion, Core FFO/share $11.24. GAAP net income is systematically depressed by heavy depreciation, and true cash earnings power is much higher than the book figure. Cash-flow quality is even stronger: operating cash flow rose steadily from $1.422 billion in 2022 to $1.671 billion in 2025, year after year; this is a genuine cash business, not one propped up by accrued earnings.

  But "incremental returns" are where this business's ceiling lies. The report uses a fairly conservative Owner Earnings basis: starting from 2025 Core FFO of $1.606 billion, deducting recurring property capex of $262 million and non-real-estate capex of about $3.17 million, yields about $1.340 billion of "owner earnings," or about $9.4–$9.6/share. Relative to invested capital (net debt plus equity), the return comes to roughly mid-to-high single digits; the traditional ROE basis is also only about 8.9% for 2025. This shows it's a business that "can earn money steadily, but every incremental dollar requires heavy capital investment first," not a low-capital, high-incremental-return model like software. And to maintain rent competitiveness, recurring property capex keeps rising (from $160 million in 2022 to $262 million in 2025), so "sitting back and spending nothing" isn't an option.

  Does it "improve or worsen with scale"? The answer is modestly improve, but the improvement comes from cost synergies rather than a leap in unit economics itself. Apartment REIT scale economics don't come from "spreading out more nationally" but from "going deeper and denser in the same high-value regions," amortizing data, technology, purchasing, and local service costs. This has been quantified in the merger: after the merger with Equity Residential, the two companies' NOI overlaps by about 95%, expected to generate about $175 million of gross synergies, or about $125 million of net operating synergies after re-assessed real estate taxes. This is a real scale dividend, but it's cost reduction (thickening FFO per share), not turning an 8%–9%-return business into a 20%-return one; the magnitude of unit economics won't leap just because of scale.

  Now for "where does the cash it earns get spent": this side is a plus for allocation discipline. In 2025 AvalonBay deployed cash in a balanced way across four channels: $1.209 billion on development/redevelopment, $682 million on acquisitions (while selling 9 communities to raise $812 million, an asset rotation), $488.1 million on stock buybacks (average price $182.20), and about $992 million on common dividends ($7.00/share). The key is that it only develops when the spread is positive and only buys back when valuations diverge, and buybacks haven't come at the cost of halting development, showing growth investment is being reinvested at a return above the cost of capital, not earnings manipulation or aimless expansion. The balance sheet can support this playbook too: Q1 2026 annualized Net Debt/Core EBITDAre is only 4.8x, Unencumbered NOI is about 95%, with no direct borrowings under the credit facility, a relatively low-leverage, sound platform within the REIT space.

  Conclusion: on the unit-economics dimension, AvalonBay is "high quality but limited elasticity." Property-level margins are high, cash flow is genuine, the balance sheet is sound, and capital allocation is rational; as a cash cow it's solid; but it's an asset-heavy, high-depreciation business requiring continuous reinvestment, with incremental returns on capital only in the mid-to-high single digits, and getting bigger delivers cost synergies rather than a qualitative shift in margins. By Baillie's yardstick of "can unit economics and incremental returns drive a compounding explosion," it's adequate but unremarkable: this is an excellent rent-collecting platform, not a high-incremental-return compounding machine.

• QWhat conditions would all need to hold true for it to rise fivefold in ten years? Are those conditions realistic? What expectations does today's stock price already imply?2/10

  A

  For AvalonBay to rise fivefold in ten years would require a string of conditions that are nearly impossible to hold simultaneously; realistically, this name essentially doesn't have "fivefold-stock" characteristics. And what today's price of about $186.59 implies is the opposite: the market is pricing in "a quality asset's fair value plus merger exchange parity," not any kind of explosive growth.

  First, let's do the math on the bar. A fivefold rise in ten years implies about 17.5% annualized stock-price compounding (or about 17.5% annualized total return including dividends). Measured against AvalonBay's history and fundamentals, that number is a stretch:

  • Historically, AVB's total return over the past ten years (with dividends reinvested) has been only about 6.8% annualized, and it's down about 12.7% over the trailing 52 weeks; it has never been a high-slope compounder.
  • Fundamental growth is low single digits: Core FFO/share rose from 9.79 to $11.24 between 2022 and 2025, about 3.5% annualized; the company's own 2026 guidance is for about +1.4% same-store revenue, about +0.1% Core FFO/share.
  • Even the report's most bullish scenario only projects a 10%–12% annualized return, and 10%–12% compounded over ten years is only about 2.6–3.1x, still far short of fivefold.

  The conditions that would all need to hold (each one is extreme):

  1. Fundamental growth doubling and sustained: same-store NOI would need to jump from the current roughly 0.2%–0.3% to a long-term 6%+ and hold it for ten years; this would require a structural leap in rent pricing power and occupancy, conflicting with the "mature slow-growth industry" nature of the business.
  2. The development engine scaling up sharply with high returns: under-development projects with an estimated total capitalized cost of about $3.39 billion would need to multiply several times over, with development yields staying persistently well above the cost of capital, but high rates are exactly what compresses that spread.
  3. Interest rates falling sharply and staying down: REIT valuations are highly dependent on long-end rates. With the 10-year Treasury currently around 4.5%+, getting the market to expand AVB's cash-flow multiple from about 16.5x to 25x+ would require sustained rate declines, a macro bet outside the company's control.
  4. A large expansion in the valuation multiple: even if FFO doubled, reaching fivefold would still require the multiple to expand from 16.5x to above 25x; both volume and price would need to rise together, with no room to miss either.
  5. Merger synergies far exceeding the framework: the about $125 million of net synergies from the EQR merger would need to multiply several times over and spark reacceleration, but synergies are fundamentally cost savings, with a limited ceiling.

  These five conditions would need to happen simultaneously, and the realism of that is extremely low. Any asset-heavy, rate-sensitive apartment REIT with low-single-digit organic growth is structurally incapable of a fivefold-in-ten-years run.

  What does today's price already imply? Not high growth, but "fair value plus event arbitrage":

  • AVB's current price of about $186.59 corresponds to about 16.5x forward Core FFO (2026 guidance Core FFO/share of about $11.00–$11.50), about 19–20x Owner Earnings, P/B of about 2.2x, and a dividend yield of about 3.82%.
  • More importantly, with the May 21 announcement of the all-stock merger with EQR (2.793 EQR shares per AVB share), the current price sits almost exactly at exchange parity. This tells you the market is primarily trading the merger terms and probability of completion, not applying a standalone-valuation discount to AVB; the implied expectation is "a well-recognized quality asset priced at merger consideration," not "an undervalued stock about to break out."

  Conclusion: by Baillie's yardstick of "what conditions would a fivefold-in-ten-years outcome require, and what does today's price already imply," AvalonBay clearly fails to qualify. Fivefold would require five gears (fundamentals, development, rates, valuation, and synergies) all meshing at high speed simultaneously, a near-zero realism; and today's price of about $186.59 already prices it as "a fair-value quality REIT plus exchange parity," leaving neither the low-basis discount a fivefold outcome would need nor any hint of explosive-growth expectations baked in. It could be a solid holding for a mid-to-high single-digit return, but it isn't a fivefold stock.

• QWhy hasn't the market caught on yet? Does it not understand, does it look down on the company, or does it lack foresight? What would become the "narrative inflection point"?3/10

  A

  This question needs to be answered in reverse for AvalonBay: the market hasn't mispriced it out of "not understanding, looking down on it, or lacking foresight"; quite the opposite, the market has actually understood it quite clearly and priced it fairly fully. So the real "narrative inflection point" isn't about when the market will "wake up and re-rate it," but about which way the two exogenous variables (the merger and interest rates) go.

  First, let's correct the implicit premise of the question. This Baillie question presupposes "there exists an undervalued truth the market hasn't recognized yet." But AvalonBay doesn't fit that premise:

  • There's no "bad-company discount." The report cites the merger materials, which, on a basis of May 20, 2026 FactSet and company data, show AVB's enterprise value at about $35 billion, already first-tier among apartment REITs; the market is giving it "quality-asset fair value."
  • There's no obvious valuation gap. The current price of about $186.59 corresponds to about 16.5x forward Core FFO, about 19–20x Owner Earnings, and P/B of about 2.2x, landing inside the report's "reasonable intrinsic value range of $170–$205/share," broadly fair and not mispriced.
  • The merger has already made the value explicit. After the May 21 announcement of the all-stock merger with EQR, the current price sits almost exactly at exchange parity (2.793 EQR shares per AVB share), showing the market is precisely trading "the merger terms and probability of completion," not ignoring its value.

  In other words, the market neither "doesn't understand" AvalonBay (REITs are among the most thoroughly researched asset classes), nor "looks down on it" (it's given a leading-name valuation), nor "lacks foresight" (the long-term value of merger synergies is already factored into the price). It's being priced fully, not overlooked.

  So what's the one truth that might not be fully priced in yet? It's the asset replacement value the report points to: book value per share was about $82.9 at the end of 2025, but that's a conservative floor after historical-cost depreciation: the evidence being that AVB sold 9 communities in 2025 for $812 million, generating a $335.7 million GAAP gain on disposition, and sold another 3 communities in Q1 2026 for $341 million, generating a $179.7 million gain. True private-market value clearly exceeds book value. This might be the one small sliver where "the market hasn't looked quite far enough," but it's already largely reflected in the merger premium and analysts' NAV estimates, and doesn't amount to "significant undervaluation."

  What will the real "narrative inflection point" be? Not "the market finally gets it," but exogenous variables rewriting the story:

  1. The direction of interest rates. REIT valuation levels are highly dependent on long-end rates. The current 10-year Treasury of about 4.5%+ is suppressing multiples; if rates trend down, AVB's cash-flow multiple could re-rate upward from about 16.5x; this is the biggest narrative switch, and it's not within the company's control. Conversely, if rates keep rising, multiple expansion becomes harder.
  2. Whether the merger succeeds or fails. This is the most direct inflection point: if the merger completes smoothly and synergies (about $125 million net, realized within 18 months) come through, the story shifts to "a bigger, denser platform"; if the merger fails and AVB's stock price quickly diverges from exchange parity, that would inversely expose the market's true judgment of AVB's standalone value; this is the real litmus test of whether today's price is inflated.
  3. A turn in fundamentals. Same-store NOI is currently growing only about 0.2%, with expenses tight. If supply gets absorbed and rent pricing power recovers, pushing same-store NOI back above 4%, the narrative would shift from "transition year" to "reacceleration"; if NOI turns negative for consecutive periods, it would be re-rated downward.

  Conclusion: the honest answer on this dimension for AvalonBay is that it isn't "an opportunity the market hasn't caught onto yet"; it's a thoroughly researched, fully priced, quality REIT currently in the middle of a merger event. The "perception gap" this Baillie question is looking for essentially doesn't exist here; its stock price won't re-rate because "the market suddenly gets it"; it will only move up or down with the three exogenous variables of rate direction, merger outcome, and a turn in fundamentals. For a growth investor, this means there's no "bargain only I can see" to be had; you're buying a good company at a fair price, betting on macro and event outcomes, not on a perception gap.
