So it might be worthwhile to
- export variables for subshells
- replace single by double quotes, but make sure double quotes intended for the subshell are escaped.
Thanks for the pointer. I thought it would be something to do with that. I've got it working now after exporting $2 before calling the subshell.

Code:
#!/bin/bash
BRANCH=$2
export BRANCH
echo "Checking out branch $BRANCH"
find . -type d -name .git -exec sh -c 'cd "$1"/../ && pwd && git checkout "$BRANCH" && git pull; echo "Branch being passed in: $BRANCH"' _ '{}' "$BRANCH" \;

STG-BRANCH(1)							   StGit Manual 						     STG-BRANCH(1)

NAME
stg-branch - Branch operations: switch, list, create, rename, delete, ... SYNOPSIS
stg branch stg branch <branch> stg branch --list stg branch --create <new-branch> [<committish>] stg branch --clone [<new-branch>] stg branch --rename <old-name> <new-name> stg branch --protect [<branch>] stg branch --unprotect [<branch>] stg branch --delete [--force] <branch> stg branch --description=<description> [<branch>] DESCRIPTION
Create, clone, switch between, rename, or delete development branches within a git repository. stg branch Display the name of the current branch. stg branch <branch> Switch to the given branch. OPTIONS
-l, --list List each branch in the current repository, followed by its branch description (if any). The current branch is prefixed with >. Branches that have been initialized for StGit (with linkstg:init[]) are prefixed with s. Protected branches are prefixed with p. -c, --create Create (and switch to) a new branch. The new branch is already initialized as an StGit patch stack, so you do not have to run linkstg:init[] manually. If you give a committish argument, the new branch is based there; otherwise, it is based at the current HEAD. StGit will try to detect the branch off of which the new branch is forked, as well as the remote repository from which that parent branch is taken (if any), so that running linkstg:pull[] will automatically pull new commits from the correct branch. It will warn if it cannot guess the parent branch (e.g. if you do not specify a branch name as committish). --clone Clone the current branch, under the name <new-branch> if specified, or using the current branch's name plus a timestamp. The description of the new branch is set to tell it is a clone of the current branch. The parent information of the new branch is copied from the current branch. -r, --rename Rename an existing branch. -p, --protect Prevent StGit from modifying a branch -- either the current one, or one named on the command line. -u, --unprotect Allow StGit to modify a branch -- either the current one, or one named on the command line. This undoes the effect of an earlier stg branch --protect command. --delete Delete the named branch. If there are any patches left in the branch, StGit will refuse to delete it unless you give the --force flag. A protected branch cannot be deleted; it must be unprotected first (see --unprotect above). If you delete the current branch, you are switched to the "master" branch, if it exists. -d DESCRIPTION, --description DESCRIPTION Set the branch description. --force Force a delete when the series is not empty.

Part of the StGit suite - see linkman:stg[1] StGit 03/13/2012 STG-BRANCH(1)
