Why MTSI Stock dropped -7.14% Today — RQD Quant Desk Flash

Per the Roarable RQD rating, MTSI scores 56 out of 100, a D+ grade with the verdict "Roarable Sell — Weak Fundamentals / Trim." The five pillars are: Fundamental Cash Engine 14/20 (ROIC 6.5%; FCF yield 1%), Whale 13F Flow 7/20 (institutional accumulation and options positioning), Insider Conviction 12/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit 9/20 (Beta 1.23; sector sensitivity), and Forensic Balance Sheet 14/20 (Altman Z 16.42; Piotroski F 7/9; Debt/Equity 0.25). The weakest pillars are institutional flow and macro regime fit, both scoring below half of their 20-point maximum. The strongest pillars, cash engine and balance sheet, each score 14, which suggests the business is not structurally distressed on paper even though its earnings-based return metrics are modest. For a prospective investor, the rating frames the stock as one where balance-sheet quality offers some support, but where thin cash yield, a high-beta profile, and weak institutional momentum argue for caution and valuation discipline at the current price. This is an analytical reading of the RQD score, not a recommendation to buy or sell.

Per the SEC financials, revenue rose from $648.4M (FY 2023) to $967.3M (FY 2025), while FY 2025 net income turned negative at $-54.2M despite positive operating income of $129.7M. The market data reports a net margin of -5.6% and an operating margin of 13.4%, with ROIC at 6.5%. Per the Roarable RQD rating, the Altman Z-Score is 16.42, the Piotroski F-Score is 7/9, and Debt/Equity is 0.25, which together point to a balance sheet the rating treats as sound. Reported debt figures differ materially across the periods shown, and the FY 2023 cash value is not available in source data.
