This vehicle has finished, so there is no window to file a cash-per-share figure for and none will follow. No estimate is shown in its place.
Nothing dated is on file. That is an absence in the record, not a statement that nothing is coming.
Yield to redemption
Nothing left to redeem — no yield to compute.
This SPAC has finished — its trust was paid back or used to close the deal, so there is nothing left to redeem and no yield to compute. A yield to redemption is a claim that you can hand these shares back for the trust cash. That account is closed, so this page will not print a number here.

The company
from SEC filingsRead the full profile
Star Peak Energy Acquisition Corp. was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker STPK. The company priced its initial public offering on August 19, 2020, under SEC file number 333-240267, with shares registered for cash on S-1 0001104659-20-089149 and a pricing prospectus filed as 424B4 0001104659-20-096940. Its SEC CIK is 0001758766 and its SIC industry code is 7373 (Services-Computer Integrated Systems Design). The ticker STPK appears on the cover page of a 10-Q filed on November 16, 2020 (accession 0001104659-20-125801). The vehicle completed a business combination and no longer files, with its closed status established by an 8-K filed on May 4, 2021 (accession 0001104659-21-061061) reporting a change in shell company status under item 5.06. EDGAR now files this CIK under the name STEM, INC.
Material findings
from the full read of every filingEvery document this company files gets read whole — body and exhibits. These are the ones the read flagged as material, newest first, each citing its filing.
The entire swing from prior-year net income to this year's loss is the absence of last year's $220.0 million debt-extinguishment gain; the operating loss actually halved. Liabilities are nearly twice total assets, with $319.2 million of notes outstanding.
Revenue is falling because the company is shedding low-margin battery hardware resale, and margins and adjusted EBITDA are rising as a result; the reported net loss reverses only because last year's quarter carried a one-time debt gain.
The trigger is documented: on August 28, 2024 the company received written notice from the NYSE that it was not in compliance with the minimum average closing price required for continued listing, so the split is a cure rather than a preference, and 166,358,775 shares outstanding is the base it would compress. Leadership changed hands during the same stretch — Mr. Buzby served as Interim CEO and Executive Chair until January 27, 2025, and Mr. Doran became Chief Financial Officer and Executive VP effective September 2, 2024.
Nothing a stockholder votes on changed, and the proxy statement/consent solicitation statement/prospectus is not in this document, so a reader must go to the version that carries it. What the retained fee table still shows is the shape of the issuance: of 64,999,790 Class A shares, 53,775,396 answer Stem's outstanding common stock after conversion of all its preferred, convertible securities and certain warrants, and 11,224,394 answer options and warrants. The shares are priced at $14.88 for fee purposes, on December 9, 2020 trading, and the fee was previously paid.
Consideration remains a fixed pool of approximately 65,000,000 New Stem shares less whatever stays issuable under Stem options and warrants that survive the merger, so the ratio moves with Stem's own share count rather than with the value of the deal. The stated 0.216 assumes all Stem preferred has converted, substantially all Stem warrants have converted, and 51,735,290 option and warrant shares are assumed by STPK and remain outstanding at closing; fractional entitlements are paid in cash at $10.00. The record date, and so the assumed effective date, is still blank.
The consideration is a fixed pool rather than a per-share ratio: existing Stem common stock is cancelled for a pro rata portion of approximately 65,000,000 shares of New Stem Common Stock, less any shares issuable on options and warrants of Stem that remain outstanding after the merger — so every option or warrant left alive reduces what the common holders receive. The registered count splits into 53,775,396 shares for Stem's common stock after conversion of all preferred and convertible securities, and 11,224,394 for those surviving options and warrants.

Two amendments in, the size of the issuance has not moved, so a STPK holder's dilution is settled and what remains open is the closing conditions and the redemption election. Stem's holders still take a pro rata portion of approximately 65,000,000 shares, less whatever remains issuable under options and warrants that survive the merger, so the per-share outcome turns on how much of the fixed pool those holders absorb. The $14.88 basis remains the December 9, 2020 average of the high and low sales prices, used solely to compute the fee.
Consideration is a fixed pool of approximately 65,000,000 New Stem shares less whatever remains issuable under options and warrants that survive the merger, so Stem's own overhang comes out of its shareholders' share of that pool rather than adding to it. On the stated assumptions — all preferred converted, substantially all warrants converted, and 51,735,290 option and warrant shares assumed and left outstanding — the exchange ratio would have been approximately 0.217 New Stem shares per existing Stem share, with fractional entitlements paid in cash at $10.00.
Stem's holders take a pro rata portion of approximately 65,000,000 shares, reduced by whatever remains issuable under options and warrants that survive the merger, so the pool is fixed and the per-share outcome moves with how much of it option and warrant holders take. On the stated assumptions the exchange ratio would be approximately 0.217 of a share for each existing Stem share, and those assumptions include 51,735,290 shares under existing Stem options and warrants being assumed by STPK and staying outstanding at closing. The fee uses $14.88, the December 9, 2020 average.

In plain English
tap a term to open itEvery piece of jargon this page could have used, and what it actually means.
Open the plain-English guide
No floor / floorlessthe cash guarantee is gone — the price is unprotected
A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.
Redemption deadlinethe last day to hand shares back for cash
Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.
Broker action datethe day your broker needs the instruction — earlier than the official date
Brokers batch redemption instructions to the transfer agent, so the practical cutoff is roughly two business days before the published deadline. This is the date that actually costs people the floor.
Cash in trust / trust per sharethe cash the company is holding for each public share
Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.
Trust discountbuying below the cash held for you
Only meaningful while a redemption right exists. On a floorless name the same arithmetic is not a discount, it is the market pricing distress, and this product will not call it a yield.
Dilutionhow much of the company new shares take from you
Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.
Pro-forma equitywhat the company is valued at once the deal closes
The combined company's equity value assuming the announced terms and the redemptions that have actually happened.
ARShow much upside you get per unit of downside
SpacBrain's asymmetric-return score. It is deterministic — the same inputs always produce the same number — and it is capped, not zeroed, when the floor is gone.
De-SPACthe day the SPAC becomes the real company
The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.
Outside datethe contractual long-stop for closing the deal
A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.
Accession numberthe SEC's unique id for one filing
Every figure on this page carries the accession of the filing that states it, so you can open the primary document rather than trust us.
Accreted NAV (estimate)the last filed cash figure, plus the interest it should have earned since
A model, not a filing: last filed value compounded at the 3-month T-bill for the days elapsed. Always shown in italic with the word estimate, and never printed beside a filed number without it.

admitted from EDGAR's QUARTERLY FORM INDEX, walked without any SIC filter. The SIC 6770 census could not reach this registrant: EDGAR reassigns a shell's SIC the day it stops being one, and this CIK now files under 7373 (Services-Computer Integrated Systems Design). The screen found it by filing SHAPE instead — S-1 2020-07-31 → 8-A12B 2020-08-17 → 424B4 2020-08-19 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-240267, which belongs to S-1 0001104659-20-089149 (2020-07-31) — a registration of shares sold for CASH, which is what makes it an IPO rather than merger consideration. Blank-check status from the registrant's own first-person sentence in that prospectus (EDGAR full-text search, 424B4 2020-08-19). Ending PROVEN, not inferred: CLOSED per 8-K 0001104659-21-061061 (2021-05-04) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,3.03,5.01,5.02,5.03,5.06,9.01). EDGAR now files this CIK as "STEM, INC." — the SPAC's own name is kept here and the successor is the target. ipoSizeM and deadline left NULL: gross-proceeds prose conflates the over-allotment with the offering, and a charter deadline belonging to a vehicle that has ended is a date nobody can act on. ipoDate is the 424B pricing date.
