Reading the filings
Arithmetic on what Sentinel Energy Services Inc. has disclosed, written the way a desk would read it. These are observations, not a rating. Nothing here scores the vehicle or implies a view on it.
Trust versus the $10 unit
The trust holds $10.33 per public share, 3.3% above the $10.00 the units were sold at. That spread is accrued interest on the trust and, where the charter provides for it, sponsor contributions paid in to buy more time. It is the floor a public shareholder can redeem at, not a valuation of the business.
Sponsor promote
The sponsor's founder block is 1,125,000 shares against 34,499,655 public shares, or 3.2% of the combined count, acquired before the IPO at nominal cost. That promote is the structural dilution every public shareholder carries into a combination, and it is why the economics of a de-SPAC differ so sharply from a conventional IPO.
Warrant coverage
Each unit carried one-third warrant per unit. Warrants are dilution deferred: they cost the holder nothing until exercised, and they overhang the post-combination share count. Thinner coverage is generally a sign of a stronger book at pricing.
Sponsor record
Sentinel Management has launched 2 vehicles. Of the 2 that have resolved, 2 closed a combination and 0 liquidated, a 100% completion rate. A sponsor's record is not a forecast, but it does tell you whether the team has taken a deal across the line before.
Underwriting
Citigroup led the offering. It has been named on 170 SPAC IPOs, book-running 114 of them, and 53.6% of its resolved vehicles closed a deal. The syndicate has no control over whether a sponsor finds a target, but the quality of the book at pricing shapes who ends up holding the units.
Filings per month since the first one. A vehicle that has gone quiet with a deadline ahead is a different proposition from one that is still working.

Sentinel Energy Services Inc.: questions answered
What is Sentinel Energy Services Inc.?
Sentinel Energy Services Inc. is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001709768. It completed its initial public offering in Nov 2017, raising $345M in gross proceeds. The vehicle is sponsored by Sentinel Management through Sentinel Management Holdings, LLC. The mandate targets energy. Business combination closed; the company trades under a new ticker.
How much does Sentinel Energy Services Inc. hold in trust?
Approximately $356,228,094, or about $10.33 per public share, as at the most recent filing on record. Trust balances move: shareholders redeem at extension votes and at the combination vote, and sponsors pay contributions in to extend. Treat the figure as a point-in-time disclosure, not a running balance.
When must Sentinel Energy Services Inc. complete a merger?
No combination deadline appears in the filings we have indexed. The date is stated in the charter and repeated in each quarterly report; where our parser could not establish it with confidence we leave it blank rather than infer one.
What happens if Sentinel Energy Services Inc. does not find a target in time?
The charter requires the vehicle to redeem 100% of the public shares and return the trust, pro rata, to public shareholders. That is the mechanism working as designed rather than a default. Founder shares and warrants are worthless in that outcome, which is why the sponsor's incentive is to get a deal done or to buy more time. Across the market, deadline lapsed without a deal; trust returned to public shareholders.
Can I redeem shares in Sentinel Energy Services Inc., and at what price?
Public shareholders may elect to redeem in connection with a combination vote and at each extension vote, at the pro-rata trust value on the relevant record date, most recently disclosed at about $10.33 per share. Redemption is a right attached to the public shares only; warrants and rights carry no claim on the trust. The mechanics and the deadline for electing are set out in the proxy statement for the vote in question.
Is the trust value the same as the share price for Sentinel Energy Services Inc.?
No. Trust per share is a disclosed, contractual figure: what a redeeming holder receives. The market price is whatever the shares change hands at, which can sit above the trust when a deal is well received or below it when the market doubts one will close. We do not have a current quote for this vehicle, so no spread is shown.
How much dilution do Sentinel Energy Services Inc.'s founder shares and warrants create?
The founder block is 1,125,000 shares against 34,499,655 public shares, so roughly 3.2% of the combined count sits with the sponsor at nominal cost. Each unit also carried one-third warrant per unit, which is dilution deferred until exercise. Both are disclosed in the prospectus and both survive into the combined company, which is why a de-SPAC at $10 is not economically the same as an IPO at $10.
Who sponsors Sentinel Energy Services Inc., and what is their track record?
Sentinel Management Holdings, LLC is the sponsor entity, part of the Sentinel Management franchise. That franchise has launched 2 vehicles in total, of which 2 closed a combination and 0 liquidated, a 100% completion rate on resolved vehicles. Named principals: Andrew Gould, Krishna Shivram.
Which banks underwrote the Sentinel Energy Services Inc. IPO?
Citigroup, Goldman Sachs, Credit Suisse. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Sentinel Energy Services Inc. a good investment?
That is not a question this site answers. Sentinel Energy Services Inc. is covered here as reference data: what the company filed, when it filed it, and what the numbers in those filings say. The Edge, FOMO and Potential scores on this page are derived measures with a published formula, not ratings of investment merit: they describe the setup, and every component is shown so you can take them apart. We publish no price targets and no recommendations, and nothing here should be read as advice. The figures are a starting point for your own work, and each one carries the accession number of the filing it came from.
Where does this Sentinel Energy Services Inc. data come from?
Filings Sentinel Energy Services Inc. submitted to the SEC under CIK 0001709768: the registration statement and final prospectus for the structure, quarterly and annual reports for the trust, current reports and proxy statements for deals, votes and extensions. Trust economics are taken from the registrant's own XBRL tags rather than parsed from prose, which is why they are exact. Every filing in the history above is listed with its accession number, which identifies the document uniquely on EDGAR; Pro accounts open it directly from the row.

Every figure on this page is read from documents the registrants filed with the U.S. Securities and Exchange Commission, principally the IPO prospectus (Form 424B4), quarterly and annual reports, current reports and proxy statements, the registrant's own XBRL tags for trust economics. Nothing is sourced from press coverage, from the companies themselves, or from a third-party aggregator. Where a filing does not disclose something, the field is left blank rather than estimated.
