Motorcar Parts of America, Inc. (MPAA) Income Statement

Growth has proven episodic rather than cumulative: seven of ten quarters expanded, yet both 2026Q3 and 2027Q1 contracted by roughly 10%, so the sequential strength in 2026Q4 and 2026Q2 appears to reflect shipment or order timing rather than durable share gains. The absence of three consecutive positive quarters suggests investors should treat any forward revenue acceleration as unproven until the pattern repeats, particularly given that the two largest quarterly declines are the most recent observations in the series.

The 790 basis point swing from 24.1% in 2025Q3 to 16.2% in 2027Q1 is unusually wide for a parts manufacturer and may indicate that mix, input costs, or warranty exposure are driving results more than pricing power, which would make margin recovery less within management's control. Against Dorman's 41.1%, MPAA's sub-20% baseline leaves limited room to absorb cost inflation, and the fact that the weakest margin coincides with the weakest revenue quarter suggests operating leverage is now working in reverse rather than cushioning the downturn.

With R&D steady at roughly $3.2M and SG&A ranging between $18.9M and $24.3M regardless of volume, the cost base appears predominantly fixed, which means incremental revenue should be highly accretive but also implies that further volume contraction would compress operating income at an amplified rate. The 10.6% operating margin earned in 2026Q4 demonstrates the earnings power available when volume and gross margin align, yet 2027Q1's 2.1% margin indicates that the recovery in fixed-cost absorption has not yet become self-sustaining.
