The Short Version

Applied Optoelectronics, a Texas company, makes parts that carry data as pulses of light through glass fiber cables. The huge computer warehouses that power artificial intelligence need more of these parts every year.

The company just finished selling about $600 million of brand-new stock. This is its third stock sale this year. Most of the money will buy factory machines so it can make more of these parts.

The catch is that every new share makes each existing owner’s slice of the company a little smaller. Shareholders are paying for this expansion before it has earned anything.

Applied Optoelectronics, Inc. (NASDAQ: AAOI), known as AOI, said in a release distributed via PR Newswire on October 5, 2026 that it has completed its $600 million “at-the-market” equity offering program. An at-the-market program lets a company sell newly issued shares gradually into the open market at prevailing prices. AOI sold 5,694,845 shares at an average price of $105.36, for proceeds of $587,999,985.89 after commissions and fees.

The Sugar Land, Texas-based maker of optical and HFC (hybrid fiber-coaxial, the network design cable operators use) networking products first disclosed the program on August 21, 2026, when it filed a prospectus supplement with the U.S. Securities and Exchange Commission. Chief executive Dr. Thompson Lin described it as the company’s third at-the-market program this year.

Executive Summary

AOI has raised roughly $588 million in net proceeds by selling stock in about six and a half weeks. It intends to spend the money primarily on expanding manufacturing of optical devices for data centers. Those devices convert electrical signals into light and back, so data can travel over fiber between the servers and switches in AI computing clusters. The company says the money will go to “new equipment and machinery for production and research and development use” as it scales its manufacturing capacity. Formally, the proceeds are designated for general corporate purposes that may also include debt repayment and working capital.

This matters because it shows how one AI-exposed component supplier is paying for growth. The company is not using contracted customer funding or debt that it has disclosed. It is selling new shares while its stock commands a high price, and then using that cash to buy production equipment. Doing this three times in one year is a pattern rather than an opportunistic one-off. AOI has chosen to build capacity ahead of revenue and to let shareholders carry the up-front cost through dilution.

Shareholders Are Fronting the Factory Build

The headline mechanism is straightforward. Building optical components at scale requires buying production and test equipment before the products it makes can be sold. AOI is paying for that gap with equity. Net proceeds of about $588 million are earmarked “primarily in support of its manufacturing expansion efforts for data center optical devices.” Lin framed the raise as supporting the company’s “ability to address growing demand for high-speed optical connectivity in AI data centers.” That makes the link between the capital and the AI buildout explicit. This was the third at-the-market program of 2026, so equity issuance has become a recurring funding channel for the expansion rather than a single balance-sheet top-up.

The trade-off is dilution. AOI issued 5,694,845 new shares, and every one of them reduces existing holders’ percentage ownership of future profits. The bet is that the new capacity will earn back more per share than the dilution costs. That depends on utilization: whether the added lines run full on orders at acceptable prices. Equity carries no interest or repayment schedule, which makes it a forgiving way to fund capacity whose payback timing is uncertain. In return, the company gives up a share of the upside permanently instead of temporarily.

Several groups are affected. Existing AOI shareholders absorb the dilution. Hyperscale and cloud buyers, the very large operators of AI data centers, stand to gain another expanding supply source for optical links if the capacity comes online. Competing optics suppliers face a better-capitalized rival that is adding production.

What the Offering Mechanics Reveal

The numbers say something about market appetite. At the $105.36 average price, 5,694,845 shares come to roughly $600 million gross, essentially the full program cap. Net proceeds of about $588 million imply commissions and fees of around $12 million, or roughly 2%. Selling the full $600 million between the August 21 disclosure and the October 5 completion shows the market absorbed a large volume of new stock over about 45 days without the program stalling short of its cap.

An at-the-market program differs from a traditional follow-on offering. In a follow-on, a company prices a large block at a discount in one night. An ATM drips shares into normal trading, which usually costs less and lets the company sell more when the price is strong. The flip side is that investors face continuous supply of new stock while a program is open. With three programs in one year, that overhang has been a near-constant feature of the stock in 2026.

Capacity Is the Bet, Customer Concentration Is the Risk

Capacity only pays if it is used. AOI’s own risk disclosures in the announcement are frank about what could undermine utilization. They list reduced customer orders, “the company’s reliance on a small number of customers for a substantial portion of its revenues,” potential pricing pressure, and changes in the rate of design wins. A design win is when a customer selects a supplier’s part for a product. When a few buyers dominate revenue, a shift in one buyer’s deployment plans can leave expensive new equipment underused.

Geography adds another variable. AOI manufactures at its Sugar Land headquarters and in Taipei, Taiwan, and Ningbo, China, and its risk factors cite tariffs, international trade regulation, and economic conditions in the United States and China. Where the new machinery is installed will shape its cost base and its exposure to trade policy. The equity raise has secured the funding. Whether that funding becomes profitable output depends on order flow and on where the equipment is placed.

Background

Applied Optoelectronics, Inc. is headquartered in Sugar Land, Texas, and trades on Nasdaq under the ticker AAOI. It develops and manufactures optical and hybrid fiber-coaxial networking products and describes them as building blocks for AI data centers, cable TV and broadband fiber access networks. It sells to what it calls tier-one customers in cloud computing, CATV broadband, telecom, and fiber-to-the-home markets. Its R&D is in Atlanta, and it manufactures in Sugar Land, Taipei, and Ningbo.

The company has said it relies on a small number of customers for a substantial share of its revenue, which is common among suppliers to large cloud operators. As AI computing clusters grow, demand for high-speed optical connectivity inside data centers has become a central part of AOI’s pitch to investors. In 2026 the company has repeatedly turned to at-the-market stock sales to fund manufacturing expansion aimed at that demand.

The Short Version

Shares in two companies building small, factory-made nuclear reactors jumped on Thursday. Oklo rose about 13% and NuScale about 10%.

The trigger was a vote in the US House of Representatives on how to power the huge computer warehouses behind artificial intelligence. The bill does not require anyone to use nuclear power.

That gap matters. Oklo had just arranged to sell up to $1 billion of new stock to fund its reactors. A higher share price means it can raise that money while handing out fewer new shares.

Shares of small modular reactor developers Oklo and NuScale Power rose sharply on Thursday after the U.S. House voted on legislation addressing electricity supply for data centers. Yahoo Finance and 24/7 Wall St. reported Oklo up 13% and NuScale up 10%. TechStock² put the gains at 11% and 9% and reported that the measure stops short of ordering the use of nuclear power. Other nuclear names, including NANO Nuclear Energy and fuel supplier Centrus Energy, also rose.

The rally came one week after Oklo disclosed, in an 8-K filed September 11, an equity distribution agreement with ten banks. The agreement lets it sell up to $1 billion of Class A common stock “at the market,” meaning gradually and at prevailing share prices.

Executive Summary

The House vote gave nuclear equities a policy signal, not a purchase order. The bill as reported does not compel data centers or utilities to buy nuclear power. It does not fund a reactor. It does not change how quickly the Nuclear Regulatory Commission licenses one. Even so, investors marked up the whole small-reactor group in a single session. That shows how much of these companies’ value rests on expectations about Washington’s direction rather than on operating assets. Neither Oklo nor NuScale yet runs a commercial reactor in the United States.

For Oklo, the timing turns a sentiment move into a financing variable. Its new at-the-market program sells shares at whatever the market is paying. A higher price lets the company raise the same dollars while issuing fewer shares, which means less dilution for existing holders. The company can also choose to raise more. For AI data-center developers hoping small reactors will eventually supply firm power, a well-funded developer matters. The capital to build is the first thing between a reactor design and a delivered megawatt.

A Rally on a Signal, Not a Mandate

The central fact of Thursday’s trade is the mismatch between the policy and the price move. The House measure concerns power for data centers, the warehouse-scale computing sites whose electricity demand has climbed with AI training and inference. The measure reportedly does not order that any of that power come from nuclear plants. Investors bid the sector up anyway. The best reading is that the market is pricing direction: Congress is treating data-center power as a legislative priority, and nuclear is the carbon-free, always-on source most often named alongside it.

That is a reasonable thing to be optimistic about, but it is not a revenue event. Small modular reactors (SMRs) are nuclear units far smaller than conventional plants, designed to be built in factories and installed in modules. They still have to clear licensing, secure fuel, finance construction and sign binding power contracts before they produce anything a data center can buy. A vote that addresses none of those steps directly moved the stocks by roughly a tenth. That tells readers more about how these valuations are built than about how soon reactors will run.

Why the Jump Matters Most to Oklo’s Share Sales

Oklo’s September 11 8-K sets out the mechanism. Under the equity distribution agreement, ten banks, including Goldman Sachs, BofA Securities, Citigroup, J.P. Morgan and Morgan Stanley, can sell Class A shares for Oklo in ordinary market trades, block trades or negotiated deals. Sales happen “at market prices prevailing at the time of sale,” up to $1 billion in gross proceeds. Oklo sets a daily maximum and a minimum acceptable price, and pays commissions of up to 1.5%. On the full $1 billion, that would be up to $15 million.

Because the price floats, the share price directly sets the cost of this capital to existing owners. Take any fixed dollar amount raised at a price 13% higher: it requires about 11.5% fewer new shares than it would have the day before (1 divided by 1.13). A policy-driven rally therefore does something concrete for Oklo that it does not do for a company without an open program. It cuts the dilution attached to funding reactor development, or lets Oklo raise more for the same dilution. The 8-K describes the shares as issued off a shelf registration declared effective in December 2025. That means Oklo can act on the higher price without a fresh registration process.

Two caveats keep this honest. Oklo has not said whether it has sold any shares under the program or at what prices. And a price gain built on a signal can reverse as quickly as it came. The benefit is real only for sales made while the higher price holds. Existing shareholders are the other affected party. Every share sold dilutes them, whatever the price.

A Basket Move, Not Company News

The breadth of the rally points to sector sentiment rather than company-specific developments. NuScale filed no material report with the SEC in the days around the vote. NANO Nuclear Energy’s most recent 8-K, filed September 17, reports only routine results from its September 15 annual meeting: six directors re-elected and Withum ratified as auditor. Nothing in that filing concerns the House bill, customers or reactors. When developers at different stages, and a fuel supplier, rise together on the same day, the market is repricing the theme, not the individual businesses.

For data-center developers and hyperscalers, the largest cloud operators, the practical lesson is to separate equity momentum from procurement reality. The gating items for nuclear-supplied AI capacity have not moved: licensed designs, fuel supply, construction financing and signed offtake agreements. Offtake agreements are long-term contracts to buy a plant’s output. A stronger share price can help with one of these, financing, and only for companies positioned to tap it.

Background

Oklo went public in 2024 through a merger with AltC Acquisition Corp., a blank-check company co-founded by Sam Altman. It is developing the Aurora, a compact fast reactor. Its first combined license application was denied by the Nuclear Regulatory Commission in 2022, and it has since been working back through licensing. NuScale Power’s design was the first small modular reactor design certified by the NRC. Its flagship Carbon Free Power Project with Utah municipal utilities was cancelled in 2023 after subscriptions fell short.

Both companies have positioned themselves as future suppliers of firm, carbon-free electricity to data centers, whose power needs have grown quickly with AI workloads. Both remain pre-revenue on commercial reactor sales. That leaves their share prices sensitive to policy news, to financing conditions and to any sign that large power buyers will commit.
