Fundamentals · FY2026 Valuation

Standard valuation multiples from SEC-reported GAAP financials (trailing twelve months), each compared to the median for —. We use reported GAAP, not forward or adjusted earnings, so our figures can sit higher than sites that do — especially for companies with falling profit. Relative context — not a target price or investment advice.

P/E
23.82
no sector median
how it's calculated
P/E = price ÷ earnings per share
$100.46 ÷ $4.22 = 23.82
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.
P/B
5.0
no sector median
how it's calculated
P/B = price ÷ book value per share
$100.46 ÷ $20.10 = 5.0
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.
EV/EBITDA
17.55
no sector median
how it's calculated
EV/EBITDA = (market cap + net debt) ÷ EBITDA — net cash lowers EV
($6.6B − $0.0B net cash) ÷ $0.4B = $6.5B ÷ $0.4B = 17.55
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.

4 trades Recent Congressional Trades

Two things to watch per trade: the disclosure lag (how many days passed before the trade was made public) and the price move in that window (how the stock moved during those non-public days). A sell followed by a price drop, or a buy followed by a rise, means well-timed trading — visible here in the open. Note: the Score measures how notable a trade is, not whether it made money — the price move is shown for context and isn't part of it.

Corporate insiders · SEC Form 4 Insider Activity

What the company's own officers and directors did in LNTH — open-market purchases and sales from SEC Form 4 filings (option exercises, grants and tax withholding are excluded). This is context for the congressional activity above, never a buy/sell signal, and the two datasets are kept separate on purpose. Does convergence mean anything? →
