Market Insights Snapshot
In May 2026, CAM’s category mix concentrated further in Flower at 84.71% share while holding rank 1 in Flower in California; within this anchor, Flower grew 41.29% year over year and 1.59% month over month, while Pre-Roll, at 12.64% share, rose 59.89% year over year but fell 4.98% month over month. Smaller bets diverged: Vapor Pens slid 53.38% year over year but rebounded 11.44% month over month to 1.50% share, and Edible declined 3.82% year over year and 12.25% month over month to 1.14% share; this tilt, alongside an 11.49% year-over-year drop in average price, implies CAM is defending Flower volume and letting non-core categories act as opportunistic adjacencies rather than growth pillars.
The mix signals a positioning choice: maintaining a category-dominant footprint in Flower (rank 1 in California) while using Pre-Roll’s 59.89% year-over-year lift to extend reach without diluting the core, even as its 4.98% month-over-month dip flags tactical promo or shelf volatility. With Vapor Pens shrinking 53.38% year over year despite an 11.44% month-over-month bounce, and Edible contracting both year over year (3.82%) and month over month (12.25%), the portfolio points to a deliberate depth-over-breadth stance that trades diversification for price-managed share capture in Flower amid a lower average price down 11.49% year over year.
Competitive Landscape
CAM is ranked #1 in CA Flower in May 2026 after climbing from #4 year over year, and up from #3 in February 2026, while reaching its peak rank of #1 in May 2026; this places it ahead of STIIIZY at #2 despite that competitor’s 39.7% YoY sales growth, and ahead of CannaBiotix (CBX) at #3 amid that brand’s -8.3% YoY sales change. The rank ascent from #4 to #1 over twelve months and from #3 to #1 over three months, coupled with competitors moving in opposite directions (+39.7% for STIIIZY versus -8.3% for CannaBiotix), implies CAM’s share gains are driven more by relative velocity and distribution advantages than category lift alone, signaling durable leadership pressure on the #2 and #3 positions.

Notable Products
Jack Herer (3.5g) posted the steepest decline in May 2026 at -18.2% and slid to rank 2, while Jack Herer Pre-Roll (1g) fell -14.7% at rank 5, indicating brand equity for the Jack Herer name is not translating evenly across formats. Private Reserve - Bubba's Girl (3.5g) grew 8.4% to hold rank 1 and Bubba's Girl (7g) added 7.1% at rank 4, and with eight of the top ten coming from the Flower category this tilt signals prioritization of larger-format and premium flower over Pre-Roll recovery. Private Reserve - Kush Mints (3.5g) advanced 36.0% at rank 3 against a -39.9% drop for Bubba's Girl Pre-Roll (1g) at rank 7, and the $496,656 from Private Reserve - Bubba's Girl (3.5g) concentrates revenue in a single SKU. The pattern implies CAM is consolidating around premium Flower while legacy names in Pre-Roll are being deprioritized or facing distribution gaps.
