Mobix Labs' S-1 registers 6 million resale shares for Kips Bay, 20% of its float, as it calls a turnaround

Mobix Labs'▼−1.08% — Mobix Labs, down 1.08 percent today fiscal Q4 news was everywhere on November 10: revenue up 129% sequentially to about $1.81 million, gross margin more than tripling from 12.9% to 44.5%, product revenue up 171% ¹². What no outlet wrote about is the filing. At 4 p.m. that same day, the SEC declared effective the company's Form S-1↗, File No ⁴⁶. 333-299747; EDGAR, the SEC's filing database, recorded the effectiveness notice on November 12 ⁴⁶. The same week, the company put out a 120-day momentum update↗ touting doubled revenue and new fighter-jet orders ⁵.

The shares being freed are not the company's to sell

Read the S-1 itself: it is not an offering by the company ⁶. It registers the resale of up to 6,000,000 Class A shares by one selling stockholder, Kips Bay Select, LP, issuable on conversion of Series A 10% convertible preferred stock ⁶. The company receives nothing from those sales, though it may take in up to $9.8 million if Kips exercises its preferred warrants ⁶.

The registered shares would be roughly 20.3% of the 23,576,570 Class A shares outstanding as of October 14 ⁶. At the 58-cent close, that is about $3.5 million of stock against a $10.4 million market cap ³. And the registration sits on top of a financing already running: Kips has converted 4,959 preferred shares into 5,870,187 common shares, and the company has already taken $2.2 million of warrant proceeds ⁶.

The conversion terms grow as the stock price falls

The terms matter more than the count. Kips paid $2.0 million on May 19, 2026, for preferred shares carrying $2.4 million of stated value, plus warrants for more preferred stock ⁶. The conversion price floats at 82% of the lowest volume-weighted average price (VWAP) over the prior eight trading days, and the stated value automatically grows when the market price sits below the conversion price ⁶. The S-1's own risk factors call this combination potentially "substantial and potentially continuing dilution" ⁶.

The release's comparisons skip the year-ago quarter

The release's comparisons↗ are sequential for a reason. Year over year, fourth-quarter revenue fell about 4%, and the 44.5% margin sits under last year's 50.5% ². Fiscal 2026 closed with a preliminary GAAP net loss of about $41.86 million; the fourth quarter's $9.09 million net loss was smaller than the prior quarter's $16.8 million but still about five times the quarter's revenue ². The company discloses substantial doubt about its ability to continue as a going concern ¹². Shares closed at 58 cents, a $10.4 million market cap ³.

So the scoreboard reads: a recovery quarter smaller than the year-ago quarter, still deeply loss-making, financed by a structure that mints the fund more shares as the price falls. Management calls it a turnaround; the S-1 says the turnaround will be paid for by whoever owns the float ². All the Q4 figures are preliminary and unaudited, with final results due in the Form 10-K ². What to watch next is that audited 10-K and its final share count, plus any further Kips Bay conversion or sale filings ².
