When AI Growth Leaves Each Share Earning Less
The arithmetic of equity raises and convertible debt, plus a five-line funding test for your next investment review.
A business earns 12.5% more, yet earnings per share fall 10% because its share count rises faster than its profit. Our worked example shows exactly when a $500m equity raise helps existing owners and when it leaves them worse off on earnings per share.
The question is what the new capital earns after its full cost. Start with the financing facts, follow the arithmetic, then apply the five-line test to one holding.
THE ANNOUNCED STARTING POINT
CoreWeave’s 17 September announcement proposes $3bn of convertible notes, potentially extended by $500m, due 1 April 2033. The company can settle conversion in cash, shares or both. Final pricing was not specified in that release.
A separate agreement permits sales of up to 35 million shares, including forward arrangements that do not initially deliver proceeds to CoreWeave. Record the date cash becomes usable, not merely the date a programme is announced.
The calculations that follow use an invented company and simplified terms. They illustrate a method, not a CoreWeave valuation. Announced financing and completed cash receipts remain separate throughout.
FOUR NUMBERS TO KEEP SEPARATE
Measure | What to record | Common mistake |
Gross financing | Face value of new debt or share-sale proceeds. | Calling all of it deployable cash. |
Net usable cash | Cash actually available after fees and other uses. | Ignoring hedging costs or restricted cash. |
Future claims | Interest, repayment and potential equity issuance. | Treating a low coupon as the full cost. |
Return per share | Value or cash attributable to each common share. | Assuming revenue growth creates equal shareholder growth. |
My starting point: judge the project and the financing together. Then calculate what each existing share owns.
A WORKED EXAMPLE OF EQUITY FINANCING
All figures are hypothetical. A company has 100m shares and produces $200m of annual earnings available to common shareholders. Earnings per share are $2.00. It sells 25m new shares at $20 to raise $500m before fees. Assume the proceeds are invested immediately, with no other changes.
Annual steady-state outcome | Before raise | Weak project | Break-even | Strong project |
New project net earnings | $0m | $25m | $50m | $100m |
Total common earnings | $200m | $225m | $250m | $300m |
Shares outstanding | 100m | 125m | 125m | 125m |
Earnings per share | $2.00 | $1.80 | $2.00 | $2.40 |
EPS change | Baseline | −10% | 0% | +20% |
The share count rises 25%; original holders’ ownership falls 20%, from 100% to 80%. To preserve $2.00 EPS, annual earnings must rise by $50m. That is a 10% incremental earnings yield on the $500m raised.
Preserving EPS is the first hurdle, not proof of value creation. Timing, risk and cash investment still matter. Reaching $50m after several years is worth less than earning it immediately.
Cash received is not value destroyed
New shares bring in cash. If they are issued at fair value and the proceeds earn a fair return, original owners can retain roughly the same value per share despite owning a smaller percentage.
Value is lost by issuing too cheaply, overpaying for assets or earning too little on the proceeds. EPS arithmetic reveals the hurdle; discounted cash flows tell us whether clearing it creates value.
Timing changes the funding requirement
If the project takes two years to earn revenue, staff and other commitments still need funding. Include those cash outflows. If another raise is necessary, its dilution belongs in today’s investment decision.
A simple funding worksheet
Start with unrestricted cash. Add expected operating receipts and completed financing; subtract operating payments, taxes, interest, maturities and committed investment. Keep uncertain financing in a separate scenario. If using operating cash flow, do not subtract expenses already included in it.
Schedule the largest bills monthly or quarterly. A positive year-end balance can hide a midyear cash shortfall.
WHY A CONVERTIBLE NEEDS TWO SCENARIOS
A convertible gives its investor debt rights plus an option to convert. A low coupon can reflect the value of that option. Model the debt outcome and the equity outcome separately.
For a simplified example, assume $500m of notes, a 3% annual coupon and a $25 conversion price. Ignore fees, tax, accrued interest at conversion, call provisions and hedges. These terms are invented and are not CoreWeave’s announced or final terms.
Case | Cash obligation | Potential equity effect |
Debt remains outstanding | $15m annual coupon; $500m principal at maturity. | No shares from conversion in this case. |
Full principal converts into shares | Principal is exchanged for equity under the assumed terms. | 20m shares: $500m ÷ $25. |
Company settles in cash | Cash required depends on contractual settlement terms. | May avoid shares, but consumes liquidity. |
Starting with 100m original shares, full conversion produces 120m shares; the original holders own 83.3%. Do not also leave the entire $500m principal outstanding in that scenario. That counts the same claim twice.
The downside still needs a repayment plan
A strong share price makes conversion more relevant. A weak price can leave the debt outstanding and cash due at maturity. “The notes probably convert” is not a refinancing plan.
ADVANCED DETAIL Capped calls and reconciliation
CoreWeave plans to use some proceeds for capped calls. These hedges can offset conversion-related dilution or cash costs within contractual limits. Include their upfront cost, strike, cap and counterparty exposure before estimating the net effect.
Count the hedge cost in cash needs and its valid offset in conversion scenarios. A hedge neither eliminates every dilution outcome nor deserves to be ignored.
For a full model, reconcile the pricing announcement, note terms and financial statements. Record net proceeds, coupon, maturity, conversion price, settlement choices and hedge cost. For equity programmes, reconcile authorised shares, actual sales and cash received.
Mark unresolved terms as unknown and test a range. Precision in the arithmetic cannot repair a missing assumption.
CONNECT THE FINANCING TO THE ASSET
Financing buys time and capacity. Follow each project through construction, energisation, customer acceptance, collections and equipment replacement. Delays push receipts back while fixed obligations continue.
Test | Evidence to request | Downside case to model |
Delivery | Site milestones and customer acceptance conditions. | Capacity starts earning six months later. |
Demand | Committed volume, duration and cancellation rights. | Utilisation is lower at renewal. |
Economics | Cash contribution after power and support. | Prices fall while contracted costs persist. |
Replacement | Hardware refresh schedule and payer. | Useful economic life is shorter than planned. |
Liquidity | Available cash and dated obligations. | No additional equity raise is available. |
These are analyst-selected stress tests. Run each separately, then combine a coherent adverse case rather than treating every worst outcome as likely.
USE THE SAME DISCIPLINE ACROSS THE AI CHAIN
Equipment suppliers: follow orders into inventory, shipment, acceptance and cash. Check whether deposits cover production and service costs reduce margins. Growth can absorb working capital before it improves cash flow.
Software: include implementation, inference costs and employee equity. Robotics: include installation, maintenance and human intervention. Apply the same economic question using each business’s actual cash cycle.
TURN THE ANALYSIS INTO A DECISION
The case strengthens when funding lasts through customer acceptance and project returns justify the cost, leaving attractive value per share. It weakens when completing existing commitments depends on generous future issuance prices.
The bull case: early capital secures scarce equipment and accelerates delivery. If those benefits create more value than financing costs, existing shareholders win. Dilution is a cost to measure, not an automatic veto.
