Mueller Industries Inc. (MLI) — RQD Stock Rating Cockpit

The Roarable RQD rating is 67 (grade C+), labeled "Roarable Hold — Upper Neutral / Watch for Breakout," per the Roarable RQD rating. Across its five pillars:

• Fundamental cash engine: 17 / 20. Per the Roarable RQD rating, this pillar reflects ROIC of 41.1% and an FCF yield of 4.67%. For an investor, the high return on invested capital points to strong capital efficiency, while the FCF yield indicates the free cash generated relative to the current price.
• Whale 13F flow: 5 / 20. Per the Roarable RQD rating, this pillar, covering institutional accumulation and options positioning, scores low. The source data does not provide 13F or options detail, so the reason for the weak score cannot be traced further.
• Insider conviction: 18 / 20. Per the Roarable RQD rating, this pillar reflects SEC Form 4 and Congressional PTR cluster flow and scores high. The underlying transactions are not itemized in the source data.
• Macro regime fit: 9 / 20. Per the Roarable RQD rating, this reflects beta of 1.1 and sector sensitivity. For an investor, the beta above 1.0 means the stock is modeled to move somewhat more than the broad market, which can amplify both gains and drawdowns in a risk-off environment.
• Forensic balance sheet: 18 / 20. Per the Roarable RQD rating, this reflects Altman Z 18.71, Piotroski F 8/9, and Debt/Equity 0.5. These are strong readings that suggest low financial distress risk.

Taken together, the profile shows a financially sturdy business with strong cash and balance-sheet metrics, offset by weak institutional flow and a macro-sensitivity score that leaves the stock in a "hold" band rather than a clear buy signal. The valuation inputs (P/E TTM 15.9, forward P/E 14.8) sit in the moderate range per the market data, so upside depends on whether the fundamental strength translates into improved institutional and macro sentiment. The label itself points to a "watch for breakout" posture rather than an immediate action signal.

Per the SEC financials, revenue, operating income, net income, and free cash flow rose across the three reported fiscal years, and debt moved from $1564.8M in FY 2023 to $0.0M in both FY 2024 and FY 2025. Per the market data, operating margin is 22.9% and net margin is 18.3%, with gross margin listed as 0%. Per the Roarable RQD rating, ROIC is 41.1%, the Altman Z-Score is 18.71, the Piotroski F-Score is 8/9, and Debt/Equity is 0.5. EPS for the reported periods is listed as N/A in the SEC financials.

Per the recent news feed, the dominant theme is negative price action following fiscal Q3 results:

• Multiple headlines (RED-flagged, "RISK WATCH") reference margin pressure and a stock drop after Q3 results, including a report of a four-month low and a report describing a mixed Q3 earnings print and an estimate miss.
• Several YELLOW "MARKET WIRE" items cover the same earnings-driven move, including a TradingKey report of a 9.91% decline on Oct 20.
• One Benzinga item is a long-horizon performance piece and carries no near-term catalyst.

Per the Butterfly Supply-Chain Graph, no supply-chain links or proprietary signals are recorded (supply chain: NONE; links and signals empty). The news items are headline-level only and do not provide the underlying margin figures or guidance details.

• Why is the gross margin listed as 0%, and does this reflect a data-definition issue or an actual reporting pattern?

• What were the FY 2023 cash balance and the EPS figures, which are listed as N/A or absent in the SEC financials?
