Sources:13D/A by Carlos Slim Helu (Apr 30, 2026) ↗All of the company's proxy statements on EDGAR ↗

13F percentages divide the shares each institution reports by the Class A shares outstanding on the cover of the company's latest report before the quarter end (May 15, 2026). Entities of the same group file separately and are not added up. With more than one share class, a 13D or 13G counts shares convertible from another class as owned, so we do not show its percentage. We hold 13D and 13G filings made since Dec 23, 2024: a holder above 5% that has not filed since then does not appear here.

Prokidney revenue

Prokidney reported annual revenue of $893,000 for fiscal year 2025 (year ended December 31, 2025), according to its Form 10-K filed with the SEC (XBRL data).

Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.

Quality vs sector
—

This company's sector comes from its SIC code, unreviewed, or has too few comparable companies: we do not compare it with its sector.

Figures from the statements the company filed with the SEC (10-K, 10-Q). Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M. How each figure is calculated

Earnings quality and debt

Operating cash flow ÷ net income (12 months)
no datanot calculated with negative net income
Interest coverage (operating income ÷ interest)
−41,252 timesnegative operating income
Debt due within 12 months
$17.0K0.00 times cash and investments

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.
