Symbotic (SYM): 90.5% Of Revenue Is One Customer

Symbotic Inc. (SYM) Q3 FY2026 — Fiscal Q3 2026 (quarter ended June 27, 2026): revenue $720.8M, up 21.7% and ~0.8% ahead of a $715.0M estimate. Class A diluted EPS $0.09 against a $0.1311 consensus - a 31% MISS. Net income $55.0M vs a $21.2M loss, but $43.3M of it was allocated to noncontrolling interests and $19.4M was a non-cash gain on strategic investments. Adjusted EBITDA $95.2M, more than double. Free cash flow MINUS $164.6M. Q4 guide $760-780M vs a $777.5M consensus. Stock -14.88% to $39.60. Symbotic's fiscal Q3 2026 looked fine on the surface - revenue up 21.7%, gross margin from 18.9% to 22.3%, adjusted EBITDA more than doubled to $95.2M, and a swing from a $21.2M loss to $55.0M of net income with no debt at all. The stock fell 14.9% anyway. This episode is about three things in the filing that did not make the headlines. First, Note 4: one customer - Walmart - was 90.5% of revenue this quarter, up from 83.8% a year ago. That is a record, and concentration is rising, not falling. Second, $19.4M of the $55.0M of net income (35%) was a non-cash fair-value mark on privately held strategic investments; strip it and Class A EPS is about 5.9 cents, not 9, making the miss ~55% rather than 31%. Third, Part I Item 4 says disclosure controls were NOT effective as of June 27, 2026 because of an unremediated material weakness over the timing of cost-of-revenue recognition - the exact process that produces the celebrated gross-margin expansion. Free cash flow was MINUS $164.6M, and the $1,746M cash pile is matched by $1,737M of customer prepayments. THE CALL: AVOID (4/5, A REAL BUSINESS AT A PRICE THAT NEEDS 28.6% GROWTH FOR A DECADE) — base-case value ~$16.0 vs ~$39.6 today. KEY METRICS: - CALL: AVOID 4/5, fair value ~$16 vs the $39.60 close (-60%). Street: 18 analysts, Buy, $63.67 avg target. We DIFFER and are far more cautious. - Rev $720.8M +21.7%. Class A EPS $0.09 vs $0.1311 (a 31% miss). Adj EBITDA $95.2M. FCF MINUS $164.6M. Q4 guide $760-780M vs $777.5M street. - One customer = 90.5% of revenue (83.8% LY). $19.4M of $55.0M net income was a non-cash mark. Material weakness on cost of revenue still open. What to watch: UP: the contingent 400-system Walmart online pickup/delivery order worth over $5.0B being signed into remaining performance obligation; a concentration number that actually falls below 85% on genuine third-party revenue; remediation of the material weakness; or two consecutive quarters of positive free cash flow with deferred revenue flat or down. BEAR: another quarter of unbilled receivables growing faster than revenue; a Q4 print at the low end of the $760-780M guide; further charges on the $34.3M component replacement/recall program; or an adverse ruling in the surviving part of the Decker securities class action.
