How the RTO fit is scored

A private company can go public by merging into a company already listed — a reverse merger, or RTO. The fit says how well a listed operating company would serve as that vehicle: a 0–100 sum of seven capped sub-scores, each read from the company's own filings. It is a screen for candidates, not a recommendation.

RTO fit sub-scores for an operating company
Sub-scorePointsFull marks when
Cash vs value25Net cash (cash and short-term investments less all liabilities) at or above market value; 0 at 25% or less.
Size15Market value of $10–150M, tapering linearly to 0 at $5M and at $500M.
Wind-down20A restructuring (8-K Item 2.05) within 12 months, or R&D or revenue down 50% or more over 2 years.
Clean balance sheet15Liabilities at most 20% of assets, and no going-concern doubt.
Holder pressure10An outside Schedule 13D (not an insider) within 24 months.
Listing health10No exchange deficiency notice (8-K Item 3.01) within 12 months; 5 while a deficiency is still curable.
Mechanics5Periodic reports filed on time: no NT 10-K or NT 10-Q within 24 months.

A missing input scores 0, shown as —; it is never imputed. Listed closed-end funds and BDCs are scored too, on a set of sub-scores of their own.

Where a deal stands

Each candidate also carries a stage, read from the filings that move a deal forward.

RTO stages
StageWhen
CandidateThe default: a listed company with none of the signals below.
StirringA restructuring (8-K Item 2.05) or an outside Schedule 13D within 12 months.
In playAn 8-K Item 1.01 followed by a merger proxy (PREM14A, DEFM14A), an S-4 or a Rule 425 filing within six months; in play for 12 months after.
ConvertedThe merger completed: 8-K Items 2.01 and 5.01 in one filing, or a 2.01 followed by a name change within 30 days. The pre-merger company stays as a precedent.

What stands in the way

Friction flags mark what would complicate a merger. They are shown beside the fit, never subtracted from it.

RTO friction flags
FlagMeaning
Delisting riskAn exchange deficiency notice (8-K Item 3.01) within 12 months, or a bid-price deficiency.
Going concernThe auditor or the filer states substantial doubt about the company's ability to continue as a going concern.
LeveredLiabilities above half of total assets, which a merger has to repay or carry.
Already a shellAlready a shell: 8-K Item 5.06, the cover-page shell check box, or SIC 6770. Rule 144(i) then limits what the new holders can resell, and the 2011 seasoning rules apply before an uplisting.
Dual classMore than one class of common stock with different votes, which a merger has to collapse or carry.
