Nebius Prices $5 Billion With Its Stock Far Below Strike

Nebius Group (NBIS) priced a $5 billion senior notes offering on August 20, split between $3 billion of 0.50% convertible notes due 2030 with a $313.46 exercise price and $2 billion of 4.5% notes due 2034, while the shares last closed at $210.91.

Nebius Group (NBIS) went to the debt market on August 20 with a $5 billion senior notes offering, and the terms say as much about the company's ambitions as its funding needs. The deal came in two pieces: $3 billion of 0.50% convertible notes due 2030 and $2 billion of 4.5% notes due 2034. Depending on how the allocations and any upsizing settled, the company expects to raise between $4.9 billion and $5.7 billion. The stated purpose is straightforward — capital to expand its artificial-intelligence business, which in practice means compute capacity, and compute capacity means cash out the door long before revenue comes back in.

The number to hold onto is $313.46. That is the exercise price on the 2030 convertible tranche — the level at which those notes turn into equity rather than a repayment obligation. NBIS last closed at $210.91, down 3.75% on the day from a prior close of $219.13, with a session range of $201.89 to $213.75, as of the last trade on Monday, August 24. Put those two figures side by side and the conversion price sits roughly 48.6% above where the stock actually trades.

What the conversion price implies about the shares

A convertible note is a bond with an equity option attached. The buyer accepts a coupon far below what a straight bond would pay — 0.50% here, against 4.5% on the 2034 straight paper — in exchange for the right to convert into stock above a set price. The size and pricing of the convertible tranche therefore functions as a market signal: buyers were willing to fund $3 billion at almost no yield because they see a credible path to the shares clearing $313.46 before 2030.

That is a bullish read. It is also an expensive option for existing shareholders if it pays off. At the stated exercise price, $3 billion of convertible principal maps to roughly 9.6 million shares on an illustrative basis — the arithmetic of dividing the tranche by the strike, before any anti-dilution adjustments or hedging the company may have layered on. Holders convert only in the scenario where the stock has risen substantially, so the dilution arrives precisely when shareholders are feeling best about the position. That is the trade-off in a cheap convertible: the coupon saving is real today, the share count is contingent tomorrow.

The straight tranche is simpler and, on the surface, dearer. On an illustrative basis, the two coupons together imply roughly $105 million of annual interest — $15 million on the convertible piece and $90 million on the 2034 notes. For a company at Nebius's stage of build-out, that is a manageable carry against $5 billion of fresh capital, but it is a fixed claim on cash flows that are still being built.

The share price moved first

What is notable about the sequence is that the selling preceded the deal. The stock was changing hands around $280 in mid-August, closed the prior week at $219, and has since drifted to $210.91. That is a decline of roughly 24.7% from the mid-August level on an illustrative basis — most of it done before the notes were priced, not after. Convertible issuance often pressures a stock because arbitrage buyers short the equity to hedge the option they have just bought, but here the market appears to have anticipated the financing rather than reacted to it.

For anyone underwriting Nebius from here, the question is not whether the capital was needed. AI infrastructure is a capital-intensive business and the company said plainly that the money funds expansion. The question is whether the growth arrives on a schedule that makes the $313.46 strike look conservative, or whether shareholders end up carrying the interest without the upside. Baystreet flagged the tension in both this name and Fabrinet, and the two cases rhyme more than they look alike.

Fabrinet beat, raised, and fell anyway

Fabrinet (FN) delivered the kind of quarter that usually rewards holders. Fiscal fourth-quarter non-GAAP earnings came in at $4.10 per share on revenue of $1.32 billion, up 45.1% year over year. The optical manufacturing services provider — it builds and packages optical components for networking and data-center customers rather than selling under its own brand — then guided fiscal first-quarter non-GAAP net income to as much as $4.25 per share, an illustrative sequential step up of about 3.7% at the top end.

The stock went the other way. Shares had traded above $600 before the report and closed at $436.67 on August 21. They last closed at $421.14, down 3.56% on the day, with a range of $413.68 to $429.28. From the pre-earnings level above $600 to that last close is a drawdown of roughly 30% on an illustrative basis, using $600 as the reference point.

Nothing in the numbers explains that. What explains it is what was already in the price. Accelerating revenue and expanding margins had been the consensus expectation for months; a quarter that confirms consensus removes the reason to keep paying up for it. Management has said it has strong demand visibility and multiple growth vectors — language echoed by peer Lumentum (LITE), which last closed at $830.17, down 4.22%, after a session range of $784.47 to $844.00. The optical complex, in other words, is not signalling a demand problem. It is signalling a valuation reset.

The common thread is the cost of AI expectations

Both stories are about the same thing from opposite ends. Nebius is spending to build AI capacity and has just locked in $5 billion of it on terms that only look cheap if the equity performs. Fabrinet is already earning from the AI networking build-out and has just discovered that a 45.1% revenue increase does not automatically buy a higher multiple. The sector's operating momentum and the sector's share prices have decoupled, at least for now.

The broader tape did not help. The Nasdaq 100 proxy QQQ closed at $706.32, down 1.00% from a prior close of $713.44, while the S&P 500 tracker SPY slipped 0.29% to $763.47 and the Dow 30 fund DIA edged up 0.27% to $533.65. All three names discussed here fell more than the index, which is what usually happens to high-beta AI infrastructure when risk appetite thins.

What to watch from here

• Nebius conversion math. The distance between the market price and $313.46 is the cleanest single measure of whether the financing was well timed or expensively timed.
• Interest against build-out. The 4.5% 2034 tranche is a fixed claim. Watch whether deployed capacity starts generating revenue fast enough to cover it comfortably.
• Fabrinet's next print against $4.25. Guidance at the top end sets the bar. Hitting it may no longer be enough; the market has shown it wants more than confirmation.
• Lumentum as the read-through. If the optical peers keep guiding confidently while their shares keep sliding, the problem is positioning and multiple, not end demand.

Frequently asked questions

How much did Nebius raise and on what terms?

Nebius Group priced a $5 billion senior notes offering on August 20, split into $3 billion of 0.50% convertible notes due 2030 and $2 billion of 4.5% notes due 2034. Total proceeds are expected between $4.9 billion and $5.7 billion. The company said the capital funds expansion of its artificial-intelligence business.

What is the exercise price on the Nebius convertible notes?

The 2030 convertible tranche carries an exercise price of $313.46. That is the level above which noteholders would convert their bonds into equity rather than take repayment. With the shares last closing at $210.91 on August 24, the strike sits well above the current market price.

Why did the Nebius share price fall before the offering?

The stock traded around $280 in mid-August and closed the prior week at $219 before its most recent close of $210.91. Most of that decline happened ahead of the pricing, suggesting the market anticipated the financing. Convertible issuance can also pressure shares because hedged buyers short the equity against the option.

Why did Fabrinet stock drop after a strong quarter?

Fabrinet reported fiscal fourth-quarter non-GAAP earnings of $4.10 per share on revenue of $1.32 billion, up 45.1% year over year, and guided first-quarter non-GAAP net income to as much as $4.25 per share. The shares still fell from above $600 to a close of $436.67 on August 21, indicating expectations for margin expansion and revenue growth were already priced in.

What does dilution from a convertible note actually mean?

A convertible bond can turn into shares once the stock passes a set strike. If that happens, the company issues new equity and the existing share count rises, diluting per-share earnings. The trade-off is a much lower coupon today — 0.50% here versus 4.5% on the straight notes — in exchange for that contingent share issuance.

How does Lumentum fit into the picture?

Lumentum is a peer in the optical components market and its outlook commentary has been broadly consistent with Fabrinet's confidence in demand visibility. Its shares last closed at $830.17, down 4.22%, after a session range of $784.47 to $844.00, suggesting the sector's share weakness reflects valuation and positioning rather than deteriorating end demand.
