The LivePerson-SoundHound deal has now moved from merger-vote headlines into verified listed-options mechanics. On Friday, September 4, 2026, OCC memo 59710 set the contract adjustment for regular LPSN options, and memo 59709 set the further adjustment for legacy LPSN1 options. The key change is that traders no longer need to infer the listed-options deliverable from shareholder merger terms alone.
For regular LPSN options, OCC says the adjusted deliverable is 46 SoundHound Class A shares plus cash in lieu of 0.73 fractional SOUN shares, with the root staying LPSN on September 4 and changing to SOUN2 on Tuesday, September 8, 2026. For legacy adjusted LPSN1 contracts, OCC says the deliverable becomes 2 SOUN shares, cash in lieu of 0.8038 fractional SOUN shares, and USD 4.07 cash, with the root changing to SOUN1 on September 8.
That is a distinct new phase from the site’s earlier LivePerson coverage. Earlier this week, the main issue was whether the vote would pass and whether the merger would close on time. Now the practical issue is how an adjusted options contract behaves after the close, including fractional-share cash treatment, root changes, and delayed settlement of the cash portion until the cash-in-lieu amount is fixed.
This article is for market commentary and options education only. It is not financial advice, investment advice, trading advice, or a recommendation to buy or sell any security or options contract. Options trading involves risk and is not suitable for all investors. Corporate-action options can involve liquidity risk, early assignment risk, exercise risk, settlement risk, and misunderstanding of adjusted deliverables.

What actually changed on September 4, 2026
The transaction itself was already moving toward completion earlier in the week. LivePerson’s September 2, 2026 Form 8-K said stockholders approved the merger proposal and that the parties expected to consummate the merger on September 4, 2026. Nasdaq’s updated equity corporate-actions alert later said the merger closed prior to the market open on September 4, after LPSN had been halted following the after-hours session on September 3.
The new information is the formal OCC contract treatment:
| Contract family | September 4 status | September 8 status | Adjusted deliverable |
|---|---|---|---|
| Regular LivePerson options | LPSN remains LPSN with adjusted deliverable |
LPSN becomes SOUN2 |
46 SOUN shares plus cash in lieu of 0.73 fractional SOUN shares |
| Previously adjusted LivePerson options | LPSN1 remains LPSN1 with further adjusted deliverable |
LPSN1 becomes SOUN1 |
2 SOUN shares plus cash in lieu of 0.8038 fractional SOUN shares plus USD 4.07 cash |
Those details matter because they convert a general merger story into an exact adjusted-contract story. The shareholder merger consideration told traders what ordinary shares were expected to receive. The OCC memos tell traders what the listed-options contracts themselves reference after the close.
Why this is a distinct options phase
The earlier LivePerson article on the site made a deliberate distinction: the shareholder consideration was visible, but the formal OCC options deliverable was not yet verified. That distinction is no longer open.
Now there is an authoritative listed-options framework for both the standard contract family and the already-adjusted legacy contract family. That gives traders three new facts they did not have in a clean verified form before:
- the post-close deliverables for
LPSNandLPSN1, - the upcoming root changes to
SOUN2andSOUN1on September 8, 2026, - and OCC’s delayed-settlement treatment for the cash portion tied to fractional shares.
That is enough to justify a separate article. This is not just a repeated merger-close headline. It is a mechanics change that can affect assignment, exercise, valuation shortcuts, and how traders read a chain after the underlying stock itself has disappeared as a normal trading vehicle.
Why It Matters For Options Traders
1. The deliverable is now explicit, not implied
Before these memos, traders could infer that ordinary LivePerson shares were being converted into SoundHound stock consideration, but that was not the same thing as knowing the exact OCC options deliverable.
Now OCC says a regular contract represents 46 SOUN shares plus cash in lieu of 0.73 fractional shares. That is a critical operational difference from casually saying one LPSN contract equals 100 shares times the merger ratio. The deliverable has been rounded into whole-share and fractional-cash components at the contract level.
For LPSN1, the contract is even less intuitive because it already had a prior adjustment history. The new OCC memo says it now references 2 SOUN shares, cash in lieu of 0.8038 fractional SOUN shares, and USD 4.07 cash. Traders who assume all LivePerson option roots now behave the same way would miss that legacy wrinkle.
2. The root change matters operationally
On September 4, the contracts remain under LPSN and LPSN1 with adjusted deliverables. On September 8, they become SOUN2 and SOUN1.
That matters because a symbol change can confuse traders who are scanning a platform quickly, comparing quotes to the regular stock, or trying to understand why an option no longer maps one-for-one to a standard 100-share deliverable. A post-merger adjusted root is not a cosmetic detail. It is a warning that normal shortcut pricing logic may no longer apply.
3. Delayed settlement raises the friction level
OCC says the SOUN share component settles through NSCC, but the cash portion tied to the fractional share is delayed until the cash-in-lieu amount is determined. After that amount is known, OCC says put exercisers and call assignees will need to deliver the appropriate cash amount.
That is one of the most important practical points in the memo set. It means the settlement picture is not fully complete on day one even though the contract adjustment is already in force. A trader can understand the broad deliverable and still underestimate the operational friction created by a cash component that remains unresolved for a period.
4. Standard option heuristics become less reliable
With standard equity options, traders often think in clean 100-share terms. Adjusted merger contracts break that habit. A contract tied to 46 shares plus a later cash amount or to 2 shares plus multiple cash components does not map neatly to a simple underlying stock price times 100.
That can distort how traders interpret intrinsic value, assignment incentives, bid-ask spreads, or whether a quote looks “cheap” or “rich.” It can also lead to mistakes when traders compare the adjusted option to the headline stock price in SOUN.
5. Liquidity can matter as much as valuation
Corporate-action adjusted roots often trade less cleanly than standard front-line equity options. The existence of an official deliverable does not guarantee tight spreads, smooth exits, or efficient quotes. A correct formula and a tradable market are not the same thing.
For options traders, that means the lesson is not “the OCC memo solved everything.” The better lesson is that the memo solved the contract-definition problem while leaving the liquidity and execution problem very much alive.
How OCC says these contracts should be priced for now
Until the cash-in-lieu amount is determined, OCC says the underlying price for SOUN2 should be determined as:
SOUN2 = 0.4673 x SOUN
For SOUN1, OCC says the interim underlying price should be:
SOUN1 = 0.028038 x SOUN + 0.0407
Those formulas matter because they show how far an adjusted root can drift from a trader’s default intuition. SOUN2 is not just “SOUN with a new label,” and SOUN1 is even more specialized because it reflects a pre-existing adjusted contract plus the merger conversion.
This does not mean every broker screen will present the economics in the same way or on the same timetable. It means OCC has provided the reference logic that should anchor the adjusted-contract interpretation until the fractional-share cash amount is finalized.
Bullish, bearish, and neutral readings
Bullish interpretation
The bullish read is that uncertainty has narrowed. Once the merger actually closed and OCC set the adjusted deliverables, one major layer of contract ambiguity was removed. For traders who were worried about not knowing what the options would reference after the deal, the memos provide a clearer framework.
Bearish interpretation
The bearish read is that clarity on paper does not eliminate post-close trading friction. Adjusted roots, fractional-share cash components, delayed settlement, and thinner liquidity can all make a contract harder to trade, hedge, or value. In that reading, the memos confirm that this is now a specialized cleanup market, not a normal single-name options setup.
Neutral or risk-management interpretation
The neutral read is the most useful. The memos do not create a trade idea by themselves. They simply replace guesswork with a more exact contract map. For disciplined traders, that is valuable because it lowers one type of uncertainty while highlighting the remaining ones: cash-in-lieu timing, execution quality, and broker-specific handling.
What traders may misunderstand
“The merger ratio alone told us the option deliverable already”
Not exactly. The shareholder consideration and the listed-options deliverable are related, but they are not the same thing. OCC had to define the contract-level treatment.
“LPSN and LPSN1 now behave identically”
No. LPSN and LPSN1 are separate contract families with different adjusted deliverables and different economic profiles.
“Once the root changes to SOUN2 or SOUN1, the contracts become normal SOUN options”
No. SOUN2 and SOUN1 are adjusted roots, not standard SOUN contracts. The deliverables remain specialized.
“Delayed settlement is just administrative noise”
No. Delayed settlement can affect exercise or assignment handling, cash movements, and the real-world friction of the position.
“A post-close adjusted contract should trade with the same liquidity as a normal listed option”
Not necessarily. Corporate-action roots often trade less efficiently than standard contracts even when the deliverable is clearly defined.
What remains unknown or still open
- OCC had not yet fixed the exact cash-in-lieu amount for the fractional SOUN share components when these memos were published.
- Broker-specific handling of exercise deadlines, assignment processing, and display conventions may differ.
- Live market liquidity under
LPSN,LPSN1,SOUN2, andSOUN1can still diverge materially from theoretical valuation. - Traders still need to distinguish between the regular adjusted root and the legacy adjusted root rather than treating the entire post-merger chain as one uniform instrument.
Bottom line
The LivePerson-SoundHound story has now crossed into a more technical but more useful stage for options traders. Nasdaq says the merger closed before the market open on September 4, 2026. OCC memo 59710 says regular LPSN options now reference 46 SOUN shares plus cash in lieu of 0.73 fractional shares and will become SOUN2 on September 8. OCC memo 59709 says legacy LPSN1 contracts now reference 2 SOUN shares, cash in lieu of 0.8038 fractional shares, and USD 4.07 cash and will become SOUN1 on the same date.
That is the real shift. The contract mechanics are no longer a guess based on shareholder merger language. They are now documented. For options traders, the useful discipline is to treat that as better operational clarity, not as a promise of easy pricing, easy exits, or uniform broker handling. This is not financial advice.
