How will the issuance of 0.625 WES common units per Aris share dilute existing shareholders, and what impact will this have on EPS?
Answer Overview
The transaction announced onâŻAugustâŻ6âŻ2025 will see WesternâŻMidstream Partners, LP (ticker WES) acquire all outstanding shares of ArisâŻWaterâŻSolutions (ticker ARIS) in a 0.625âtoâ1 equityâandâcash swap.
- Each Aris share is exchanged for 0.625âŻWES common units (plus a cash component).
- The equity portion creates new WES units that are added to the existing share pool, which dilutes the ownership and earningsâperâshare (EPS) of the current WES shareholders.
Because the news release does not disclose the exact number of Aris shares outstanding, the exact dilution percentage and the precise EPS impact canât be calculated precisely from the information given. However, the mechanics of the dilution, the factors that will determine the magnitude of the dilution, and a framework for estimating the effect on EPS can be described in detail. The discussion below walks through each step, shows the formulae you would use once the missing numbers are known, and outlines the qualitative impact on EPS and shareholder value.
1. How the 0.625âtoâ1 Exchange Works
Step | Description |
---|---|
StepâŻ1 â Identify Arisâshare count | Let A = total number of Aris shares outstanding (the figure is typically disclosed in the mergerâagreement filing). |
StepâŻ2 â Calculate new WES units issued | New WES units to be issued = 0.625âŻĂâŻA. These become newlyâissued common units of the WES partnership. |
StepâŻ3 â Add to existing WES pool | Let Wâ = current number of WES common units outstanding (preâtransaction). After the merger, total outstanding units become Wâ = Wâ + 0.625âŻĂâŻA. |
StepâŻ4 â Determine dilution factor | Dilution factor = (New units) Ă· (New total) = (0.625âŻĂâŻA) / (Wâ + 0.625âŻĂâŻA). This percentage reflects how much of the postâtransaction ownership belongs to former Aris shareholders. |
StepâŻ5 â Effect on existing WES shareholders | Existing shareholders now own Wâ / Wâ of the combined company. Their ownership percentage falls by the same amount as the dilution factor (i.e., they own a smaller slice of the postâtransaction earnings and assets). |
Key Takeaway: The larger the A (Aris shares outstanding) relative to Wâ, the greater the dilution. Conversely, if WES already has a huge share base, the 0.625 multiplier may represent only a modest increase.
2. Dilutionâs Effect on EPS
2.1 EPS Before the Transaction
[
\text{EPS}_{\text{pre}} = \frac{\text{Net earnings (or EBITDA for a cashâflowâfocused metric)}}{\text{Wâ}}
]
2.2 EPS After the Transaction (ignoring synergies & cashâimpact for the moment)
[
\text{EPS}_{\text{post}} = \frac{\text{Combined net earnings}}{Wâ + 0.625\,A}
]
Assuming combined net earnings = E_W (WES earnings) + E_A (Aris earnings) (after any cashâpayment adjustments), the EPS change can be expressed as:
[
\frac{\text{EPS}{\text{post}}}{\text{EPS}{\text{pre}}}
= \frac{EW+EA}{Wâ+0.625A}\times\frac{Wâ}{E_W}
]
Simplifying:
[
\text{Relative EPS change} =
\frac{(EW+EA)}{E_W} \times \frac{Wâ}{Wâ+0.625A}
]
- The first term (((EW+EA)/E_W)) captures the earnings boost from adding Aris.
- The second term ((Wâ/(Wâ+0.625A))) captures the shareâdilution factor.
If the earnings boost exceeds the dilution factor, EPS will rise; if not, EPS will fall.
2.3 How the Cash Component Influences EPS
The deal is equityâandâcash: each Aris share receives a cash portion plus the 0.625 WES unit. The cash payment reduces the cash balance on WESâs balance sheet, which may reduce future interest income or increase financing costsâboth of which can affect net earnings. The net effect on EPS therefore depends on:
CashâRelated Impact | Effect on EPS |
---|---|
Lower cash/interest income | Reduces net earnings â lowers EPS. |
Financing of cash (e.g., debt issuance) | Adds interest expense â lowers EPS. |
Tax effects of cash | Depending on tax treatment, may raise or lower net earnings. |
The cash portion also affects shareholder value via the âcashâplusâstockâ nature of the purchase price: the cash portion does not create dilution, but it can reduce the amount of earnings attributable per share if the cash is not offset by an equivalent earnings increase (e.g., through synergies or cost savings).
3. Qualitative Impact on Existing Shareholders
Dimension | Potential Impact |
---|---|
Ownership % | Decreases in proportion to the dilution factor (see stepâ4 above). |
Control | If the dilution pushes WESâs publicâfloat above a certain threshold, there may be votingârights or governance considerations (e.g., a change in control provisions). |
EPS | Likely to dip in the nearâterm unless the combined earnings rise sufficiently to offset the increased share count. |
Market Perception | The market typically evaluates the âdilutionâadjusted EPSâ and compares it to the preâannouncement EPS trend. A modest dilution combined with a strong cashâplusâsynergies story can be positive; a large dilution with modest earnings increase can be a negative catalyst. |
Liquidity & Capital Structure | The cash outlay reduces cash reserves and may increase leverage, which could affect interest coverage and credit ratings, indirectly influencing EPS through higher financing costs. |
4. Estimating Dilution and EPS Impact â A Practical Example
Note: The numbers below are *illustrative** only. Replace A (Aris shares) and Wâ (WES shares) with the actual figures from the merger filing to get accurate results.*
Assumption | Illustrative Value |
---|---|
Aris shares outstanding (A) | 500âŻmillion |
WES current common units (Wâ) | 2.5âŻbillion |
New WES units issued | 0.625âŻĂâŻ500âŻM = 312.5âŻM |
Postâtransaction shares | 2.5âŻBâŻ+âŻ312.5âŻM = 2.8125âŻB |
Dilution factor | 312.5âŻM / 2.8125âŻB = 11.1âŻ% |
Existing ownership | 88.9âŻ% of the combined company |
Preâtransaction earnings (E_W) | $300âŻM |
Aris earnings (E_A) | $90âŻM (estimated) |
Combined earnings (ignoring cash cost) | $390âŻM |
PreâEPS | $300âŻM / 2.5âŻB = $0.12 |
PostâEPS | $390âŻM / 2.8125âŻB = $0.1386 |
% change in EPS | +15.5âŻ% (because earnings grew 30âŻ% while shares grew only 11âŻ%) |
In this example, EPS improves because the earnings boost (30âŻ%) outpaces the dilution (11âŻ%). However, if the cash outlay or debt financing reduces net earnings by $30âŻM, the EPS would be:
[
\text{Adjusted earnings} = 390âŻM - 30âŻM = 360âŻM\
\text{PostâEPS (adjusted)} = 360âŻM / 2.8125âŻB = $0.128\
\text{Î EPS} = -6.7âŻ% \text{ (vs. preâEPS)}.
]
Thus, the ultimate EPS outcome hinges on the net earnings effect after accounting for the cash payment and any synergies.
5. What You Should Do Next
- Obtain the precise share counts from the definitive agreement (SEC FormâŻ8âK / Sâ4 filing).
- Calculate the exact dilution factor: ((0.625âŻĂâŻA) / (Wâ + 0.625âŻĂâŻA)).
- Model the combined earnings: add Arisâs latest net earnings (or adjusted EBITDA) to WesternâŻMidstreamâs earnings, and then subtract the net cashâoutlay (including any interest expense from financing the cash).
- Project EPS with and without the transaction to see the range of possible outcomes.
- Run a sensitivity analysis:
- Scenario A: No synergies, cash paid from existing cash â minimal earnings impact.
- Scenario B: Cash funded by new debt â add interest expense.
- Scenario C: Synergy/ costâsaving assumptions (e.g., 5âŻ% operating expense reduction).
- Scenario A: No synergies, cash paid from existing cash â minimal earnings impact.
A detailed financial model using the above formulas will give you the precise dilution impact and the EPS change that can be communicated to shareholders, analysts, and the market.
BottomâLine Summary
- Dilution Mechanism â each Aris share creates 0.625 new WES units, which adds to the total share count and dilutes existing WES owners proportionally.
- Quantitative Impact â dilution = (\frac{0.625âŻĂâŻ\text{Aris shares}}{\text{Current WES units} + 0.625âŻĂâŻ\text{Aris shares}}).
- EPS Effect â EPS will change based on (i) the added earnings from Aris, (ii) the increase in shares, and (iii) the cashârelated reduction in net earnings. If the earnings increase outweighs the share increase, EPS rises; otherwise, it falls.
- Practical Takeaway â Without the exact share counts and earnings figures, we can only provide a framework; the precise dilution percentage and EPS change must be calculated from the actual numbers disclosed in the definitive agreement.
Use the steps and formulas above to plug in the actual numbers, and youâll be able to quantify the exact dilution and its effect on EPS for the combined company.
