how do I join grouped query results?

I am trying to join 2 query results so the each row shows the branchID, sales total and stock level by size. These 2 query's work on the own.

query 1:
SELECT     ph.BRANCH_ID ,SUM(Case when pd.SKU_CODE='01bu0906006514q001' then ph.STOCK_UNITS_FREE else 0 end) as [S],
SUM(Case when pd.SKU_CODE='01bu0906006514q002' then ph.STOCK_UNITS_FREE else 0 end) as [M],
SUM(Case when pd.SKU_CODE='01bu0906006514q003' then ph.STOCK_UNITS_FREE else 0 end) as [L],
SUM(Case when pd.SKU_CODE='01bu0906006514q004' then ph.STOCK_UNITS_FREE else 0 end) as [XL],
SUM(Case when pd.SKU_CODE='01bu0906006514q005' then ph.STOCK_UNITS_FREE else 0 end) as [XXL]  
FROM         RMIS.dbo.product_detail AS pd INNER JOIN RMIS.dbo.PRODUCT_HISTORY AS ph ON ph.SKU_ID = pd.SKU_ID
WHERE     (ph.WEEK_SELECTOR = 1100230) GROUP BY ph.BRANCH_ID

query2
SELECT SUM(CASE WHEN pmh.TXN_DATE_TIME > (GETDATE() - 360) THEN units ELSE 0 END) AS Last360,  
SUM(CASE WHEN pmh.TXN_DATE_TIME > (GETDATE() - 90) THEN units ELSE 0 END) AS Last90,
SUM(CASE WHEN pmh.TXN_DATE_TIME > (GETDATE() - 30)  THEN units ELSE 0 END) AS Last30,
SUM(CASE WHEN pmh.TXN_DATE_TIME > (GETDATE() - 7) THEN units ELSE 0 END) AS Last7, pmh.BRANCH_ID
FROM         RMIS.dbo.PM_TRANS_HEADER AS pmh INNER JOIN RMIS.dbo.PM_TRANS_SKU_DETAILS AS pmskd ON pmh.RECEIPT_ID = pmskd.RECEIPT_ID
INNER JOIN RMIS.dbo.product_detail AS pd ON pd.SKU_ID = pmskd.SKU_ID
WHERE     (pmh.FLAG = 1) AND (pmh.TRANSACTION_VOID = 0) AND (pmskd.FLAG = 1) AND (pd.SKU_CODE LIKE '01bu0906006514q%')
GROUP BY pmh.BRANCH_ID
