Alliant Energy LNT Research from a Long-Term Business Owner's Perspective

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

• QHow large is its market ceiling? Is it expanding an existing pie, or creating an entirely new market?4/10

  A

  The ceiling is not low, but the business is essentially making an existing pie thicker, not creating a new market from scratch. That is the fundamental difference between Alliant and the great growth stocks Baillie Gifford has in mind.

  Alliant's market boundaries are fixed by law and geography: through IPL and WPL, it operates regulated electricity and natural gas businesses under licenses in Iowa and Wisconsin, serving about 1.012 million electric customers and 433,000 natural gas customers at the end of 2025. This is not a business that can expand nationwide or globally through product strength. The service territory is the ceiling. The company itself has also made clear that the primary target of future capital investment is the utility business, and that non-utility platforms are not expected to be significant users of capital. So its growth is not territorial expansion; it is thickening the rate base per unit of area within fixed jurisdictions, then earning returns through regulated rates.

  What really raises the ceiling is the industry-level reacceleration of a mature sector: the U.S. Energy Information Administration (EIA) expects U.S. electricity demand to see its strongest multi-year growth since 2000, and the International Energy Agency also expects U.S. electricity demand to grow at an average annual rate of nearly 2% during 2026–2030, with about half of the incremental demand coming from data centers. For Alliant, this demand has already become concrete: as of the first quarter of 2026, the company had signed roughly 370MW of Iowa data center power supply agreements, lifting cumulative contracted data center demand to about 3.4 GW, corresponding to roughly an 11% CAGR in retail electricity sales from 2025 to 2031 and about 60% total demand growth in 2031 versus 2025. This is real load growth and will support rate base expansion over the next few years.

  But two points need to be separated honestly. First, this is demand-side support that thickens an existing pie; Alliant did not create the data center market. It merely happens to sit at the grid endpoint of compute expansion, making it a beneficiary rather than a definer. The same load dividend is being shared by a group of Midwest peers, including WEC, XEL, and MGE. Second, the company explicitly acknowledges in its risk factors that large-load projects may be delayed, canceled, or lead to overbuilding and underutilized assets, and data centers can bypass it through behind-the-meter self-supply. So this new pie is neither exclusive nor guaranteed.

  Conclusion: the ceiling has been materially lifted by data centers, but this is expanding a pie brought to the doorstep by external demand within an existing regulated jurisdiction, not creating a new market. This is a mature utility with policy and compute tailwinds, not a growth story opening up a new continent.

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

  A

  Almost certainly not. Doubling revenue over the next five years is an unrealistic target for a regulated utility. Alliant's realistic growth rate is mid-single digits, driven mainly by volume, meaning new load and rate base growth, rather than price or new businesses.

  Start with the facts to frame the speed. From 2021 to 2025, revenue grew from $3.669 billion to $4.362 billion under the 2025 annual-report basis, a cumulative five-year increase of about 19% and an annualized rate of about 3.5%. Net income attributable to common shareholders rose from $659 million to $810 million, and EPS rose from 2.63 to 3.14. Management's long-term IR target is 5%–7% annual EPS growth, with roughly 6% EPS CAGR over the past decade, and 2026 EPS guidance is $3.36–$3.46. Doubling revenue in five years would require about 15% annualized growth, more than 4 times the company's historical growth rate and far above its own earnings growth target. Under a regulated rate-setting mechanism, this is structurally unattainable.

  In terms of growth mix, nearly all growth comes from volume, and it is heavy-asset volume. The hardest incremental driver is data center load: cumulative contracted demand of about 3.4 GW, corresponding to roughly an 11% CAGR in retail electricity sales from 2025 to 2031. This is the fastest volume curve the company can point to, but even if delivered, retail electricity sales in 2031 would be about 60% above 2025, still far from doubling in five years. The price component is not market-based price taking; it is regulatory negotiation. The 2024 Iowa settlement provided an annualized $185 million base retail electric rate increase, and Wisconsin granted WPL new electric and gas rate increases for 2025 and 2026. These can offset inflation, but the pace and magnitude are set by regulators and cannot become a doubling engine. New businesses are even less relevant: non-utility revenue was only $89 million in 2025, and the company has clearly stated that it does not plan to allocate large amounts of capital there.

  This volume growth also has to be bought with cash. The 2026–2029 capital expenditure plan has been raised to $13.4 billion to support data center load. Under the report's calculation, capex intensity has climbed from about 31.9% of revenue in 2021 to 56.9% in 2025, with free cash flow negative for many consecutive years and the gap widening. In other words, its revenue growth does not get easier as it grows; the more it grows, the more capital and financing it needs.

  Conclusion: doubling in five years is unrealistic. A reasonable expectation is mid-single-digit compound growth. The engine is new load, or volume, plus regulator-approved rate recovery, or price, while new businesses are negligible. This is a stable but slow and highly capital-consuming growth machine, far removed from the Baillie Gifford standard of doubling revenue over five years.

• QFive years from now, what will take over as the next growth engine? Does this second curve exist today?3/10

  A

  Frankly, this company has no true second curve. Its growth engine has been, and will remain, the same one: regulated rate base expansion. The so-called next growth engine is more like the same engine receiving a fresh push from data center load, rather than a new curve built from scratch.

  When Baillie Gifford asks about a second curve, the point is to find a new growth pole outside the core business that can grow independently and take over five years later, such as AWS relative to Amazon's e-commerce business. Alliant's business model makes that difficult. The company clearly states that the primary target of future capital investment is the utility business, while non-utility platforms generated only $89 million of revenue in 2025 and are not expected to be significant users of capital. It is neither allowed nor intending to build a new business that can grow independently. The essence of a regulated franchise is a single loop of investing, recovering, and reinvesting within its jurisdiction.

  So what takes over in the next 5–10 years? It is an extension of the same curve, not a new curve:

  First, data centers and large-load interconnections. This is currently the closest thing to a new growth pole: cumulative contracted demand of about 3.4 GW, roughly an 11% CAGR in retail electricity sales from 2025 to 2031, and a 2026–2029 capex plan raised to $13.4 billion. But it still means putting more assets into the rate base and earning regulated returns. The engine has not changed; large customers have arrived on the load side.

  Second, ongoing capital investment in the energy transition. Wind, storage, gas-fired generation upgrades, and distribution network upgrades will continue absorbing capital over the next decade, but this is another expression of rate base expansion and does not constitute an independent second business.

  The real risk is that this extension curve could be undermined at its foundation. The company itself lists customer self-generation, third-party energy supply, behind-the-meter models, and direct purchases by large customers as risks. In other words, the most anticipated data center load could in theory bypass the grid and build its own power supply, causing investment that should have entered the rate base to fall through.

  Conclusion: there is no independent second curve today, and one is unlikely to emerge. The regulatory model locks the company into the single main curve of rate base expansion. Data center load is the strongest boost to that main curve over the next 5–10 years, but it is the same engine with a stronger throttle, not a new growth pole that can independently take over in the Baillie Gifford sense. For a defensive utility, this is not a defect; against a growth-stock standard, it does mean there is no next stop.

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

  A

  The core advantage is an institutional moat: regulatory licenses, legally defined service territories, transmission and distribution network assets, and extremely high switching costs. The moat itself is real and solid. Over the next three to five years, it will most likely remain stable and become slightly wider in specific areas, but it will neither widen rapidly nor meaningfully narrow.

  First, define the moat. It is not brand, and it is not network effects. It is a regional monopoly granted by institutions. The report breaks this down clearly: brand advantage is weak, since nobody uses electricity because they like the brand; network effects are almost nonexistent; patent and data advantages are weak. But switching costs are very high, since households and businesses cannot realistically switch electric and gas networks; channel advantage is strong, because the channel is the service territory itself; and licensing and regulatory barriers are very strong. Rates are built on a framework of prudent cost recovery and reasonable returns on invested capital. Limited competition and stable demand are the benefits; a regulator-constrained ceiling is the cost. This kind of moat is wide but shallow: hard to breach, but also hard to use for excess returns. The company's ROIC of only about 4.0% is evidence.

  Will the moat widen or narrow over the next three to five years? My judgment is stable with slight local widening, and both sides matter.

  The forces that slightly widen it: regulators have provided more targeted tools. Iowa's individual customer rate mechanism and Wisconsin's new 2025/2026 rate increases allow the company to serve large data center customers more cleanly and put the corresponding assets into the rate base. Combined with about 3.4 GW of cumulative contracted load, network assets that were originally low-growth gain more incremental utilization. This is equivalent to digging an additional channel inside the existing moat.

  The forces that prevent rapid widening and create erosion risk: the upper bound of the moat is always set by regulators. If the allowed return is reduced, the moat's width is directly compressed; the company lists a meaningful reduction in allowed ROE as a signal that would trigger reassessment. More importantly, there is technology-side risk. The company itself lists customer self-generation, third-party energy supply, behind-the-meter, and direct purchases by large customers as risks. This means the most valuable large customers can in theory bypass it and self-supply power, creating a real seepage point at the edge of the moat.

  Conclusion: this is a real and solid utility moat, deep enough to resist competition, but with a ceiling fixed by regulation. Over the next three to five years, data center load and constructive regulation should make it slightly wider in specific areas, but it will not show the kind of self-reinforcing rapid widening seen in brand or ecosystem moats. At the same time, allowed-return reductions and behind-the-meter supply must be watched as two erosion variables. In one sentence: the moat is very stable, but it is built for defense, not for attacking into excess compounding.

• QIf its core business is disrupted, does it have the DNA for self-reinvention? How does it handle mistakes and bad news?4/10

  A

  For a utility, this question needs to be answered from a different angle. Its core business is unlikely to be disrupted in the usual sense, since electricity and gas supply are necessities and demand will not disappear out of thin air. So self-reinvention DNA is not its key capability. The more useful observation is how it handles mistakes and bad news. On that point, Alliant looks relatively positive and fairly candid in its disclosures.

  Start with the probability of disruption. Baillie Gifford's question is designed for the risk that a technology company is overturned by a new paradigm. But Alliant sells essential services, and the report judges that the business will most likely still exist five years from now. It faces gradual erosion rather than business disappearance. The company itself lists behind-the-meter, customer self-generation, third-party energy supply, and direct purchases by large customers as risks. These can eat into the edges of load, but they will not make a regional grid lose its reason to exist overnight. Therefore, whether it has self-reinvention DNA is almost a false question for Alliant. What it needs is not the ability to be reborn after disruption, but the execution capability to keep modernizing assets within the regulatory framework, including renewables, storage, and gas generation upgrades. That is exactly what it has been doing, with 2026–2029 capital expenditures raised to $13.4 billion.

  The more informative question is how it handles mistakes and bad news. The evidence here is relatively positive:

  First, it proactively disclosed an unfavorable impairment. In 2024, the company clearly disclosed a $60 million pre-tax non-cash impairment because the Iowa regulator, the IUC, did not allow a return on the remaining book value of IPL's Lansing generating unit. This kind of information does not make management look good, but the company stated it directly. That is a positive signal that bad news is not being hidden.

  Second, accounting and internal controls look clean. The company received an unqualified audit opinion for 2025, internal control was effective, and it continued to conclude that disclosure controls were effective in the first quarter of 2026. The report did not identify obvious accounting-manipulation red flags. The point to watch is not fake earnings, but the complexity of regulatory accounting. The economic reality of earnings and regulatory assets/liabilities ultimately depends on whether future rates recover them as expected. That is a structural feature rather than an integrity issue.

  Third, the governance structure has constraint mechanisms. The company has an independent board chair, independent directors regularly hold executive sessions without management present, clawback provisions exist, and executives are prohibited from hedging and pledging shares. These reduce the room for reporting only good news and suppressing bad news.

  The discount is this: management and directors together own less than 1% of the company, so their economic interests are not deeply tied to shareholders. This means candor comes more from institutional constraints than from founder-like personal exposure.

  Conclusion: Alliant does not need, and basically does not possess, technology-company-style DNA for reinvention after disruption. But its business is inherently hard to disrupt, so the risk exposure in this question is low. What deserves credit is its attitude toward mistakes and bad news: it proactively booked an unfavorable impairment, received an unqualified audit opinion, and has governance constraints. Overall it appears honest and credible, with no sign of using a growth story to cover up problems, which is also the inverse indicator of one of the report's sell signals.

• QDoes management, especially the founder, have a long-term orientation and interests deeply aligned with the company? Is it willing to sacrifice current profits for five to ten years out?4/10

  A

  Management has a long-term orientation, standardized governance, and candid disclosure, which merits an upper-middle assessment. But there is no founder, interest alignment is weak, with management plus directors together owning less than 1%, and capital allocation is built around continuously investing for five to ten years out. This sacrifice of the present is more a consequence of the utility business model than an entrepreneurial choice.

  Start with long-term orientation and willingness to sacrifice today for the future. Judging by outcomes, the answer is yes, but the nature of that answer matters. The company has had negative free cash flow for years. Under the report's calculation, free cash flow was about -$1.31 billion in 2025. The 2026–2029 capital expenditure plan has been raised to $13.4 billion. Operating cash flow was $1.169 billion in 2025, while construction and acquisition expenditures reached $2.483 billion. This is the classic shape of sacrificing current cash for future rate base. But the honest point is that for a regulated utility, putting capital in first and waiting for regulatory recovery later is an internal requirement of the business model, not a brave tradeoff management makes between profit and the long term. It is simply how the business works.

  Now look at whether interests are deeply aligned with the company. This is the area that deserves the largest discount. The company has no founder, and more importantly, management and directors together own less than 1%, so their economic interests are not deeply tied to common shareholders. This is not unusual among large U.S. utilities, but it does not qualify as strong alignment. The positive offset is institutional discipline: the company has an independent board chair, independent directors regularly hold executive sessions without management, executive share ownership requirements of 6 times salary for the CEO and 1.5–4 times for other executives, clawback provisions, and bans on hedging and pledging shares. It also proactively engaged with shareholders representing about 55% of outstanding shares in 2025 and the first quarter of 2026. So alignment comes from the governance framework, not founder-like personal wealth at stake.

  Capital allocation is rational, but not centered on intrinsic value per share. The main uses of cash are reinvestment, dividends, and debt, rather than buybacks or large acquisitions. That is rational in itself. But the company has had almost no meaningful buybacks for years, and the share count has instead risen moderately: in 2023, ATM and Shareowner Direct Plan issuance brought in $246 million of equity financing. As of March 2026, shares outstanding were about 258.28 million, up about 0.48% year over year, and in March 2026 it also issued an additional 834,811 shares due to convertible-debt conversion obligations. This is the capital allocation of a cautiously financed utility, not the Munger-style allocation of buying back stock when undervalued to maximize per-share value.

  Integrity adds points: management discloses bad news directly, including the proactive $60 million impairment on the IPL Lansing unit in 2024, the audit opinion was unqualified, and no accounting red flags were found. Shareholder returns have also been steady: the 2026 dividend target was raised to $2.14 per share, up 5.4% from 2025, with 22 consecutive years of dividend increases.

  Conclusion: this is a standardized, candid, long-term management team, and governance quality is upper-middle within utilities. But its investment for the future is a necessity of the business model rather than entrepreneurial courage. Interest alignment depends on institutions rather than ownership, and capital allocation is prudent but not per-share-value oriented. Compared with Baillie Gifford's preferred image of a founder deeply aligned and willing to spend for ten years out, it looks similar on the surface but is different in substance.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable, and does it depend on harming society or regulation?6/10

  A

  If it disappeared tomorrow, customers would miss it intensely. No one in the region could instantly replace its electricity and gas supply, making this one of the most indispensable types of business. Its growth model depends heavily on regulation and is institutionally sustainable by nature. But because of that, the legitimacy of its growth is always tied to the regulatory rope. It does not harm society, but it cannot function without continued regulatory support.

  Start with indispensability, which is its strongest side. Through IPL and WPL, Alliant provides regulated electricity and natural gas to about 1.012 million electric customers and 433,000 natural gas customers in Iowa and Wisconsin. These are essential services, switching costs are extremely high, households and businesses cannot realistically switch electric and gas networks, and customer retention is close to 100%. If it disappeared tomorrow, the result would not be customer inconvenience; entire service territories would lose electricity and gas, and society would have to find an immediate operator. On the dimension of how much customers would miss it, utilities are among the highest-scoring business types. That is also the root of its ability to remain profitable even in recessionary years such as the pandemic, with net income attributable to common shareholders of $614 million in 2020 and $659 million/$686 million/$703 million/$690 million/$810 million from 2021 to 2025.

  Now consider whether the growth model is sustainable and whether it harms society or regulation. This is a two-part standard and should be separated.

  Social sustainability: relatively positive. Its growth comes from building grids, connecting load, and ensuring power supply, which aligns with social needs such as electrification and data center compute expansion. It provides a public necessity and does not rely on harming users or society for growth. Its price increases are not market-based extraction; they are reviewed and approved by regulators. The 2024 Iowa settlement provided an annualized $185 million retail electric rate increase, and Wisconsin granted WPL new rates for 2025/2026. Every dollar of price increase must pass through the regulatory process, which naturally carries public accountability.

  Regulatory sustainability: this is its critical vulnerability and a structural dependency. Its profit and balance sheet are largely built on the assumption that costs can be recovered through future rates. The report notes that the auditor identified regulatory accounting and its impact on the financial statements as a critical audit matter. This means the sustainability of growth depends less on the company itself and more on whether regulators continue allowing it to recover prudent capital expenditures and maintain reasonable allowed returns. If allowed ROE is materially reduced, which the report lists as a reassessment trigger, the growth logic will be damaged. So it does not harm regulation, but it is extremely dependent on regulation. That is a double-edged sword.

  One tension is worth highlighting: although data center load is a growth opportunity, the company itself lists behind-the-meter and customer self-generation as risks. If the most valuable large customers bypass the grid and self-supply power, the indispensability of that portion of growth will weaken.

  Conclusion: as a business judged by how much customers would miss it, Alliant sits at the strongest end of the spectrum: essential demand, monopoly, extremely high retention, and a service society would have to replace immediately if it disappeared tomorrow. Its growth model does not harm society, and regulated pricing gives it built-in public accountability, making it institutionally sustainable. The other side of the same coin is that the legitimacy of its growth and the upper bound of returns are entirely in regulators' hands. That is its deepest structural dependency.

• QWhat are the unit economics of this business, including gross margin and incremental returns? Do they improve or deteriorate as scale grows? Where does the money it earns go?4/10

  A

  The unit economics are stable but mediocre. Margins are steady and predictable, but incremental returns on capital are only moderate, with ROIC around 4%, and getting bigger does not make the business easier. The more it grows, the more money it has to spend. The money it earns mainly goes to reinvestment, dividends, and debt repayment, with almost no buybacks. This is the classic economic shape of a heavy-asset regulated utility.

  Start with margin-level unit economics: stability is its strength. Under the report's calculation, operating margin was roughly 21.7%–23.5% from 2021 to 2025, and net margin attributable to common shareholders was about 16%–19%. Profit is not built on a one-year cyclical boom, but on a continuing mechanism of regulatory recovery, investment returns, and cost pass-through. In 2025, revenue was $4.362 billion, net income attributable to common shareholders was $810 million, and EPS was $3.14. The base is stable, and volatility is explainable through weather, fuel recovery timing, and regulatory timing. This is the most valuable feature of a utility: predictability.

  But incremental return is the heart of this question, and that is where the weakness lies. Baillie Gifford wants businesses where scale increases and incremental returns on capital rise. Alliant is the opposite:

  First, returns on capital themselves are only moderate. The company's ROIC is about 4.0%. Under the report's calculation, ROE is about 11.3% and ROA about 2.6%. This is not poor for a utility, but it is not excellent. The key is that peers do not give investors cheaper valuations as compensation. The report lists CMS at about 4.36% ROIC, WEC at about 4.29%, and EVRG at about 3.84%. WEC's ROIC, about 4.34%, is even slightly higher than LNT's, while LNT's valuation is more expensive.

  Second, scale makes it heavier rather than better. Capex intensity rose from about 31.9% of revenue in 2021 to 56.9% in 2025. Free cash flow has been negative for many consecutive years, and the deficit has widened, with about -$1.31 billion in 2025 under the report's calculation. The 2026–2029 capital expenditure plan has been raised to $13.4 billion. This shows that growth does not make the business lighter; the more it grows, the more capital it must invest. Incremental returns are capped by regulated allowed ROE. Every dollar invested can earn only the return approved by regulators, with none of the scale leverage found in internet businesses.

  Where does the money it earns go? The answer is unexciting but rational: reinvestment, dividends, and debt repayment, rather than buybacks. In 2025, operating cash flow was $1.169 billion, but construction and acquisition expenditures were $2.483 billion, and common dividends were $521 million. Cash was simply not enough, so the company had to rely on debt and moderate equity financing to fill the gap. The result is that the share count has risen rather than fallen. As of March 2026, shares outstanding were about 258.28 million, up about 0.48% year over year. This is not capital allocation centered on intrinsic value per share. The dividend is the bright spot: the 2026 dividend target is $2.14 per share, with 22 consecutive years of growth. But this is a priority return of limited cash and does not change the basic condition of negative free cash flow and reliance on external financing.

  Conclusion: its unit economics are stable mediocrity. Margins are solid and predictable, but incremental returns on capital are moderate and capped by regulation. Greater scale makes the business more capital-intensive, not easier. Cash is used mainly for reinvestment and dividends, with almost no buybacks. This is the opposite of the kind of business Baillie Gifford favors, where scale raises returns and cash automatically gushes out.

• QWhat conditions must all be true for it to rise fivefold in ten years? Are those conditions realistic? What expectations are embedded in today's share price?2/10

  A

  A fivefold increase over ten years, or about 17.5% per year, is almost impossible for Alliant. It would require a chain of extremely optimistic conditions to hold at the same time, and those conditions conflict with each other. Today's share price of about $72 does not imply a fivefold imagination. It implies that stable mid-single-digit growth has been fully priced, with perhaps a slight premium. The market is buying certainty, not upside elasticity.

  First translate a fivefold increase into the required return: a fivefold share-price rise over ten years is about 17.5% annualized. For a utility, share-price return is roughly dividend yield plus EPS growth, plus or minus valuation change. The current dividend yield is about 2.96%, and the company's long-term EPS growth target is only 5%–7%. Together that is about 8%–10%, which matches the expected annualized return in the report's neutral/optimistic scenarios, at 6.5%–10.5%. To fill the remaining 7–9 percentage points, valuation would have to expand substantially, which fundamentally conflicts with the nature of a utility.

  What conditions must all be true for a fivefold outcome? Consider each in terms of realism:

  First, EPS growth would need to jump from 6% to 13%–15% and persist for ten years. This would require data center load, about 3.4 GW of cumulative contracted demand and roughly an 11% CAGR in retail electricity sales from 2025 to 2031, to be fully delivered, regulators to allow high-quality returns, and behind-the-meter self-supply not to intercept it. Even if everything goes right, 11% electricity volume growth cannot support 15% EPS growth for ten straight years. Realism: low.

  Second, valuation would need to expand by another large step. The current TTM P/E is about 22.8 times, already above most peers. For a fivefold result, the P/E would need to climb above 30 times and stay there for a long period. That is unrealistic for a utility with persistently negative free cash flow and ROIC of only about 4%. The market does not give this kind of asset growth-stock multiples. Realism: extremely low.

  Third, the capital structure must not drag shareholders down. The 2026–2029 capital expenditure plan has been raised to $13.4 billion. Under the report's calculation, interest coverage is about 1.87 times and Debt/EBITDA is about 6.38 times. The company would need to sustain high-intensity investment for ten years without meaningful dilution or deterioration in interest coverage. This is a necessary no-error condition, but it can only prevent downside; it cannot create fivefold upside.

  These three conditions must hold simultaneously, but the first condition, high growth, inevitably brings higher capex and financing needs, which in turn suppress the second condition, valuation expansion, and the third, no dilution. They are structurally at odds. So a fivefold outcome is not merely difficult; it exceeds the physical ceiling of this machine.

  What expectations are embedded in today's share price? It embeds fully priced stable growth, with a slight premium. The report estimates a reasonable intrinsic value midpoint of about $65.5, leaving the current price at about a 9% premium. Forward P/E is about 20.6 times, almost the same as the S&P 500's 21.2 times. In other words, the market has already priced in the data center tailwind plus steady dividend growth. Investors are not buying a defensive asset at a discount; they are paying an index-like price for certainty. That means upside has been pulled forward, not that fivefold potential is embedded.

  Conclusion: a fivefold rise in ten years would require high growth, valuation expansion, and no dilution to all be true at once. Those conditions conflict with each other and all exceed the physical ceiling of a utility, making the scenario extremely unrealistic. Today's price of about $72 embeds stable mid-single-digit growth plus a slight premium, with an expected annualized return in the neutral case of about 6.5%–8%. This is a name where certainty is already fully priced, not an undiscovered fivebagger.

• QWhy has the market not realized all this yet? Is it too hard to understand, too neglected, or too far out? What could become the narrative inflection point?3/10

  A

  The market actually understands it well, and it does not matter that the market does not look very far ahead. This is not a misunderstood or ignored stock; it is a mature utility that is well understood and fairly efficiently priced. The real issue is not what good thing the market has failed to recognize, but that the market has already priced in both the data center tailwind and the stable dividend story. So the honest answer for Alliant is that there is no obvious perception gap to arbitrage.

  First, reject the three types of market failure Baillie Gifford looks for:

  Too hard to understand? No. Alliant is an extremely transparent regulated utility. 2025 revenue was $4.362 billion, net income was $810 million, and EPS was $3.14. Revenue sources, regulatory mechanisms, and customer structure are all clear, and many sell-side analysts cover the stock. The current rating is neutral to buy, with an average target price of about $76–79. It is not too complex for the market to understand.

  Too neglected? Also no. It is not an overlooked small-cap orphan. It has a market capitalization of about $18.6 billion, is a Nasdaq constituent, and has substantial institutional ownership. The market is not neglecting it; if anything, it is valuing it above most peers. The report lists LNT's TTM P/E at about 22.5 times and EV/EBITDA at about 16.3 times, generally more expensive than WEC, CMS, EVRG, and AEE, while its ROIC of about 4.0% is not higher and is even slightly below WEC's. This is being valued generously, not being undervalued.

  Too far out? This is the only point with some relevance, but in the opposite direction. The long-term rate-base dividend from data center load is indeed a future story, but the market has not missed it. It may have already pulled it forward. Cumulative contracted demand of about 3.4 GW and a 2026–2029 capex plan raised to $13.4 billion are already consensus positives, and the share price rising near its 52-week high over the past year is evidence. So even if there is a far-out element, the risk is that the market has overestimated certainty of future delivery, not underestimated it.

  So what could be the narrative inflection point? For Alliant, the more likely inflection point is disproof rather than discovery.

  Downside inflection points, which are more likely: data center load is delayed or canceled, or intercepted by behind-the-meter self-supply; allowed ROE is reduced by regulators; interest coverage falls below about 1.8 times; or persistent dilution accelerates. Any of these would puncture the stable-compounding narrative and push valuation back toward the peer-group norm of 18–19 times P/E. The report estimates that this could pull the share price back to $45–55, implying about 25%–40% risk of permanent capital loss.

  Upside inflection points, which are weaker: the 3.4 GW load materializes faster than expected, regulators allow high-quality returns through individual customer rate mechanisms, and shareholder dilution remains limited. But even then, the utility valuation ceiling limits the scope for major rerating.

  Conclusion: the market neither fails to understand Alliant nor looks down on it. Pricing is fairly efficient and even somewhat expensive. This is not the kind of perception gap Baillie Gifford seeks, where the market has not yet realized something important. The more realistic narrative inflection point is downside disproof, such as load disappointment, ROE cuts, or faster dilution, rather than upside discovery. In one sentence: this is not a dusty stock waiting to be discovered; it is a defensive asset whose story has already been fully told and whose price carries a slight premium. Its margin of safety depends on waiting for a lower price, not waiting for the market to wake up.
