What is the likely magnitude and timing of any price decline due to this litigation?

Likely magnitude:

When a class‑action suit alleges that a company’s public statements were materially false, markets typically treat the news as a “sudden‑risk” catalyst. For a mid‑cap stock such as KLC (KinderCare Learning Companies, Inc.)—where the allegations imply the stock has been “inflated” by misleading statements—historical precedents (e.g., 2022‑23 biotech and consumer‑services lawsuits) suggest an initial 6‑12 % drop on the day of the filing, followed by a possible secondary dip of another 3‑5 % over the next two trading sessions as analysts and investors digest the potential liability and the likelihood of a settlement or judgment. In other words, expect an 8‑15 % cumulative decline within the first 48‑72 hours if the market has not already priced in the litigation risk.

Timing & trading set‑up:

The price impact will be most immediate—the first 30‑60 minutes after the news breaks—because the lawsuit is already public via a Business Wire release and is being highlighted in investor‑alert newsletters. Expect the opening price on the next trading day to reflect the bulk of the decline, with any further erosion occurring as the legal filing is examined by the SEC, the company’s management, and rating agencies. Traders should watch the pre‑market price action; a break of the prior day’s low (or a 4‑day moving average) will confirm the down‑trend. Consider a short‑position or a protective put with a stop just above the most recent high (or the 10‑day EMA) to manage risk. If the stock recovers quickly (e.g., rebounds 2‑3 % within the first 24 h), it may indicate that the market views the suit as a “paper” issue rather than a substantive liability, so a tight stop loss is prudent. If the drop exceeds the 10‑day average and the volume spikes >2× normal, a deeper short or a bear‑call spread could capture the continued weakness.
